Plan your life.
Block by block.
Type “gym tomorrow at 6” and it lands on your day. One timeline for your plans, notes, habits and the people you work with.
Free for Windows, Mac and Linux. No account needed to start. Why install it?
Most planners are a list that grows.
This one is a line that ends.
Open Fuidzy and you get one screen: today, laid out left to right, like a ruler. See something you're doing? Grab it and put it where you actually want it. Needs longer? Stretch it. Turned into two separate things? Split it. That's genuinely the whole app — there's no second screen hiding behind it.
There's no "workspace" to name before you're allowed to start. No decision about whether your dentist appointment is a Project, an Area, a Resource or an Archive. You just write "dentist, Thursday, 3pm" and it's there.
Five things.
Give us ninety seconds.
Your day is a ruler, not a list
Everything you're doing today is laid out in front of you, left to right, instead of buried in a scroll of checkboxes. Want to move something? Grab it and slide it. Want it to take longer? Pull the end. Turned into two things? Cut it in half. That's it — that's the whole manual. About as complicated as moving a fridge magnet, and nowhere near as complicated as the six-field form most apps make you fill in before they'll believe you're serious about going for a run.
It won't let you lie to yourself
Try to stack two things into the same slot and it says no — politely, but firmly. Not because we don't trust you. Because you only have one body, and an app that lets you double-book yourself and calls that "flexible" is just setting you up to fail by 3pm and blame yourself for it.
Genuinely need two things happening side by side? You still can — you just have to mean it, by adding a second track on purpose. Add as many as your day actually needs. Sharing a plan with other people? Everyone gets exactly one, so nobody's day can quietly bury anyone else's.
Habits, minus the guilt app
Most habit trackers are a second app that exists purely to make you feel bad about yourself at 11pm. Here, a habit is just a thing on your actual schedule that shows up every day — the same way brushing your teeth shows up in your actual bathroom, not in a separate hygiene app.
Decide you'd rather work out at 6:30 instead of 7? Move it once, and every future one follows. What already happened stays exactly as it happened — you can't quietly go back and un-skip yesterday. Turns out that's the part that actually keeps you honest.
Its name is Fui, and it isn't faking it
It has moods that shift depending on what's actually happening to you. It remembers real things — that you kept a streak, that you once told it you hate mornings, that you finally finished the thing you'd been dreading. Ask it something it genuinely doesn't know, and it tells you that, instead of confidently making something up — which, respectfully, already puts it ahead of a few chatbots you've definitely used.
Close the app. It keeps going.
Shut the window and the bunny doesn't vanish — it hops out onto your actual desktop, wanders around, and says your reminder out loud when it's genuinely due. No banner. No badge. No little red circle demanding attention it hasn't earned. Just a small thing that occasionally speaks up because it's actually time.
Write the proposal
Gym · in 40m
One screen. Work, habits and focus on the same line. The marker is now.
Close the window. It keeps going.
Install Fuidzy and the bunny lives on your desktop. Minimise the app and it hops out, wanders around, and tells you out loud when something is due — no tab to keep open, no notification to miss.
Free. Installs in a minute, no admin rights needed on Windows. The browser version works too — it just can't leave the tab.
Every other app wants you to stay logged in. We don't.
Notice how every app you already use is trying to keep you inside it a little longer? More tabs, more views, more notifications about the notifications. That's not an accident — it's the business model. Ours is the opposite bet, on purpose: the app that's happiest the moment you close it and go do something that isn't this app.
Not a slogan — it's the actual mechanic
A shared group's streak here goes up on days where everybody who showed up finished and left. You cannot raise it by grinding longer. Grinding longer is what breaks it. The only way to push it up is to help whoever's still stuck so the whole group gets to be done.
No green "active now" dot watching you. No daily target you can fail at 11pm for a number you made up at 9am. Just: did everyone get to stop. Petty in the best way, and it's the one thing on this page nobody can copy without becoming a worse business.
One app. Every kind of Tuesday.
We didn't build six versions of this. We built one, and it turns out a life planner is genuinely the same idea whether you're cramming for finals or running a two-person business out of your kitchen.
For the exam that's in six days
Lectures, deadlines, group projects, and three different chats that are somehow all about the same assignment. Put it all on one line you can actually see. And the stuff you're about to forget? It quietly comes back to you right before you would've — the same trick behind every flashcard app, built into any task, not just flashcards.
For running three people's lives, including your own
Kids' schedules, the electric bill, date night, whose turn it is to call the plumber. Share a plan with your partner without turning your relationship into a spreadsheet. Leave a note on the actual thing it's about. Know someone's genuinely swamped without needing the full story.
For the business that's still just you
Turn a page into an invoice. Draw your actual signature right on a document. Send a proposal as a real link instead of a file nobody's app can open. Client notes live next to the deadline they're attached to, not in a CRM you forgot the password to.
For people who think better with a pen
A free-roaming board for pinning ideas, sketching, dragging photos around. A drawing canvas on any task. Build your own little dashboard out of whatever you actually want to glance at — a timer, a streak, a quote, a photo of the dog. And yes, a kid can just draw on it. Nobody needs a login to scribble.
For showing up to something that already exists
Join with a code, decide how much you show — from "just tell them I'm around" to "here's everything, come help me finish it" — and you're in. No onboarding call. No reading someone else's twelve-tab wiki before you're allowed to contribute.
For actually finishing things together
Everyone's day, one shared view, no group-chat spiral and no stand-up that could've just been a glance at a screen. Ask for help on something and it syncs back the moment it's done. Nothing to configure into being "the team version" — it already is one.
Everything, in one screen
No jargon, no drag-this-to-do-that manual. Just what it actually gives you.
See your whole day at once
Not a list you scroll through hoping today's even possible. Your actual day, laid out — so you find out it's too full before you get to 6pm and fail at it.
Habits that don't guilt-trip you
Built into the same schedule as everything else. Miss a day and it's just a day — not a broken chain, not a reset to zero, not a reason to give up on the whole thing.
A timer, and actual music
Start a focus session and it quietly times how long things really take — so your next guess is better than your last — while calm background music plays, made fresh, straight off your own computer. No ads, no Spotify tab, no login.
A companion with an actual memory
It remembers what you've told it, notices how you actually work, and never invents an answer it doesn't have. Ask it something it doesn't know, and it just says so.
Share a plan, skip the group chat
Plan with your family, your team, your study group. Everyone decides for themselves how much to show — from "just tell them I'm busy" to "here's everything, come help me finish it."
Just tell it what you want
"Block two hours for the report tomorrow." "Move gym to six." "What did I miss?" Say it like a person and it acts like an assistant — and it always checks before it touches anything of yours.
Also a notebook. Also a spreadsheet.
Write full documents, or build a simple list — a client roster, a reading list, a budget — that figures out what kind of information you're typing on its own. No schema, no setup screen, no "choose a database type."
Turn anything into a real webpage
Got a recipe, a project brief, a routine worth sharing? One click makes it a real, working link anyone can open — no account on their end, nothing to install, nothing that opens looking broken.
It's on your computer. Actually yours.
Not rented from a cloud company. It lives on your machine, syncs only if you flip the switch, and can be backed up, exported or deleted for good whenever you want. Nobody's holding it hostage.
Wait, it also does that?
We got so excited explaining the timeline that we forgot to mention the rest of the app. So, quickly:
A corkboard for the stuff that doesn't fit in a line
Planning a trip, a wedding, a house move? Some things aren't a schedule — they're a mess of photos, links and half-formed ideas. Pin them to a free-roaming board, sketch on it, connect the dots. No separate app for "the messy part."
Yes, we can make you an invoice
Write it up as a page, hit export, and it's a real PDF — an invoice, a client proposal, a report, a set of meeting notes, a whole brief. That's one app doing the job of a document app, an invoicing app, and the ten minutes you'd normally lose fighting with the export settings.
It reads your files, when you ask
Attach a PDF, a spreadsheet, a screenshot of an email — and just ask about it. No copying the text into a chatbot in another tab and re-explaining what the file even is.
You get to bribe yourself, officially
Finish things, earn points, spend them on rewards you set — a takeaway, a lazy Sunday, new shoes, whatever actually works on you. Less "productivity system," more "you, tricking yourself into doing the thing, with our full blessing."
It genuinely won't let you fudge the truth
Skip a habit, then quietly decide later to go back and mark it done anyway? You can't. The record locks the moment it happens — which sounds strict until you realise it's the only reason a streak here actually means anything.
And when you're actually done, there's a game
Finished everything for the day? There's a small game built in for exactly that moment. Not because we think you should be doing something productive every waking second — the opposite. Sometimes "done" is allowed to just mean done.
things you can do in here.

That's a hundred and seventy-three. There are more — but at some point a list stops being a feature and starts being a wall, and we'd rather you just opened it.
Everything in here is the same object.
This is the whole reason a two-person app can take on two hundred of them, and it isn't a marketing position — it's an architectural one, and it's checkable.
Every other product in this field is several databases wearing a trench coat. A Notion page is not a Notion database row. A Todoist task is not a Todoist project. A Slack message is not a Slack file. Each of those is a separate type, with separate fields, separate search, separate permissions and a separate screen — which is exactly why those companies keep shipping a seventh sidebar to connect the six things they already built.
Fuidzy has one type. A task, a page, a habit, a database row, a meeting note, a file, a chart, a drawing, a voice memo, a shared plan — every one of them is a block, living in one table. And because they're the same object, anything true of one is automatically true of all of them.
A habit is a block
So it lands on the timeline, appears in search, shows on the board, exports to PDF and counts toward your streaks — without anybody building a habit feature.
A database row is a block
So a row can be scheduled, tagged, completed, given its own pages and found by ordinary search. None of that is true of a row in Notion.
A document is a block
So the brief you wrote has a start time, a duration, an owner and a deadline — because it's the same thing as the work of writing it.
Thirty-six kinds of block ship today — headings, text, checklists, tables, charts, callouts, quotes, code, galleries, images, files, voice clips, progress bars, signatures, an embedded canvas, an embedded board, and more. They all sit in the same one place, which is why there is no import step between any two features of this app. There is nothing to import. It's already the same thing.
That's the answer to "how can one app do the work of Notion and Todoist and Slack and Streaks and Miro and Day One at once." Not by building six products and bolting them together — by noticing they were always one product, and that the seams everyone else maintains are the entire reason their software keeps getting heavier.
Every other app plans your week.
This one plans your life.
Todoist ends at "today." Notion ends whenever you stop scrolling the sidebar. Most planners are built like they're embarrassed to think past Friday — because the second you plan more than a week out, their UI falls over. Ours doesn't, because a task in five years and a task in five minutes are the same block, on the same timeline, at a different zoom.
So plan the trip you're taking in 2029. Pin the thing you must not forget in March. Set a reminder that survives you closing the laptop, changing your phone, and forgetting this website exists. This isn't a habit tracker cosplaying as a life plan — it was built to hold one from the start.
Years, not days
Zoom the timeline out until a week is a pixel. Long-term plans don't get demoted to a "someday" list — they sit on the same board as this afternoon.
Sign here, for real
Build the contract, the invoice, the agreement as a page — table for the line items, text for the terms, a signature block at the bottom you draw with your actual hand. Export it as one PDF. No separate invoicing app rented for $12 a month to do a job three blocks already do.
The junk drawer, organized
Grocery runs, who's picking up the kid, the Wi-Fi password, when the boiler was last serviced — household admin is still text-based work, so it's still just blocks. Same app you plan a business quarter in.
Not a chatbot that apologizes for existing.
Most in-app AI talks like it's scared of you. Hedges, disclaimers, "I want to be helpful but." Ours has read your actual page, knows what's overdue, and will tell you so without three paragraphs of throat-clearing first. It's a companion, not a customer service script — it has a personality because a to-do list assistant with none of one is just a search bar with extra steps.
And it isn't locked to one person's screen. A Clan — your household, your team, your group project that refuses to die — shares one AI across the whole space. Everyone gets the same brain with context on everyone's work, which means you can finally answer "is anyone handling this" without opening five separate chats to ask.
It talks back
Ask it in plain English and it reads your page, not a script. It has memory, it has a stance, and it doesn't need "please" to take you seriously.
One AI, whole crew
Your Clan's companion sees the shared space the way a very attentive teammate would — not the way a bot reading a spreadsheet would.
Check on people without checking in
See what your circle is working on, what's stuck, what's done — without a single "hey just following up" message. Each share level controls exactly how much of that anyone sees, including you.
Your workspace can have a whole vibe.
A blank white timeline is a legitimate reason to not want to open an app. So don't get one. Drop a looping video behind your board — rain on a window, a fireplace, waves, whatever gets your brain to sit down and focus — and it plays quietly under everything you're doing, not instead of it.
This isn't a screensaver bolted onto a productivity app as a gimmick. It's the same canvas your tasks live on, just with somewhere nicer to live.
Blocks nest inside blocks. So build whatever.
Because every block can hold more blocks, a page isn't just a page — it's a frame you can fill with other frames. Which means the same system that holds your to-do list will, without complaint, hold a one-page pitch site, a project brief with a table of contents, or a shared plan you'd actually be comfortable showing a client. Nobody had to add a "website builder" feature. It was already sitting inside the block system, waiting for someone to nest six of them.
A page inside a page
Frame blocks hold other blocks. Build a structured landing page, a mini-site, a report with its own contents block — out of the same pieces as everything else here.
The mood board's real
A genuine canvas and moodboard live inside the same page system — drag images, sketch, pin ideas next to the tasks they belong to, instead of tab-switching to a separate app to think visually.
Say it instead of typing it
Voice recordings are a block, same as text. Talk your thought out, drop it on the page, keep moving — transcribe it later or just leave it as audio.
And when it needs to leave the app — a client, a printer, a filing cabinet that still exists for some reason — export the page as a real PDF, headers and tables and all, or print it. In, out, no format tax either way.
We didn't build the thing that does one job well.
We built the thing that does your life.
Whatever the other app on your screen does, there's a block for that here already. Planning, notes, files, tracking, sharing, motivation, the lot — one app, not the six you've quietly collected trying to feel organised.
Free. All of it.

- The full timeline — drag, split, stretch, ripple
- As many lanes as your day needs
- Habits, streaks, focus sessions
- Every theme
- Clans: start one or join one
- Type a plan and it lands on your day
FAQ
Is there a mobile app?
Not yet, and we're not going to be coy about it. Today Fuidzy is a Windows desktop app plus a web version that works in any browser. A phone app is on the list, not on the shelf.
Is it really free, or is this the part where there's a catch?
Really free, with no card and no account needed to start. Everything is open while we grow. If paid extras ever arrive, what you made stays yours either way.
What happens to my data?
Your tasks live in a local database on your own machine. Signing in creates an account so your subscription and handle follow you between installs. Cloud sync of task data is a separate switch, off by default. Full detail in the privacy policy below.
Are you affiliated with any app on this page?
No. Not with Notion, Slack, Microsoft, Todoist, Obsidian, Motion, or any of the other sixty. Everything said about them here is opinion and commentary, written by people who use most of them.
Why is there a bunny?
Because a to-do list is a slightly bleak object, and a to-do list with a small creature that's pleased when you finish something is measurably less bleak. It also solved a real design problem: we needed reminders that don't feel like system notifications, and a character saying it out loud turned out to be the answer.
Will the bunny be annoying?
It reads which window is in front to work out whether you're busy, and stays quiet when you are — that reading is used once and thrown away, never stored or sent anywhere. It also learns which hours you're usually heads-down and only ever uses that to speak less. If it's still too much, it can be turned off entirely.
I've read this whole page. Is that normal?
No. But we wrote about sixty app comparisons and a history of web design into a landing page, so between us, neither of us is behaving normally here.
All productivity & planning apps
MOGGED BY US
Nearly two hundred of them.
We do what every single one does. Easier.
This is the whole field — planning, notes, chat, habits, journaling, tracking, the works. We're not going to pretend we haven't heard of any of them, and we're not going to nerd out over which one has a slightly better keyboard shortcut. That's a fight for people with too much time and not enough life.
Here's the actual point: whatever the app is, whatever it organises, files, tracks or plans — a block already does that, and it does it without making you learn a second app to get there. Notion organises your files into a database. Cool. Guess what a block does. Trello gives you a board. We've got one, and ours knows what time it is. This isn't a price comparison. It's not even close.
Workspaces & note apps
14 toolsThe "second brain" category. Enormously powerful, and the category most likely to become a hobby that replaces the work it was meant to organise.
To-do lists & task managers
9 toolsThese are genuinely good at capturing what needs doing. Almost none of them are good at telling you when — a list has no width, so nothing in it can be too long to fit in a day.
Project & team management
9 toolsBuilt for organisations reporting upward. If you're a person, a couple, or three friends building something, most of this category is a suit that doesn't fit.
Team chat
5 toolsThe category that turned "a colleague had a thought" into a notification with its own sound design.
Calendars & time blocking
10 toolsThis is the category closest to what we do — and the most expensive one on the page.
Habit trackers
6 toolsReporting on this category is consistent and slightly grim: a large share of users abandon their tracker within thirty days, usually right after one broken streak resets a long chain to zero.
Journaling apps
4 toolsThe consistent reason people stop journaling isn't laziness — it's blank page anxiety, plus the feeling that you're writing the same surface-level day again.
Focus & time tracking
4 toolsTwo different promises here: help me start, and tell me where it went.
Whiteboards & canvases
3 toolsSpatial thinking tools. We have a canvas too, but ours has an axis that means something.
Docs & collaborative writing
6 toolsWhere the words go. None of them has an opinion about when you'll write them.
More note apps
6 toolsThe long tail of capture. Four apps — Evernote, Notion, Roam and Obsidian — hold over 75% of the student market between them, but these are the ones people actually switch to.
More task & planner apps
6 toolsThe ones that show up in every "best to-do app" list. Several are excellent. All of them are lists.
Time tracking & analytics
5 toolsThese tell you where the time went. Ours tries to be right about where it's going.
Focus & digital wellbeing
5 toolsThe apps you install to protect you from the other apps. Which should tell you something about the category.
Email & the inbox-as-task-list
9 toolsMost people's real task manager is their inbox. That's the problem these tools optimise; it's the problem we delete.
Read-later & research
9 toolsThe pile of things you swore you'd read. Every one of these is excellent at saving and hopeless at making you actually sit down and read.
Writing apps
9 toolsWhere the words happen. We're not trying to replace a novelist's tool — we're trying to be the reason you opened it at 9am.
Spreadsheets & databases
8 toolsWhere structured work goes to become somebody's second job maintaining it.
Meeting notes & transcription
6 toolsA booming category built entirely on the premise that meetings produce work nobody writes down.
Proposals & business documents
7 toolsDocuments you send to people who pay you. Most of this category is a template plus a PDF button plus a subscription.
Mind mapping & visual thinking
6 toolsThinking in shapes. We have the canvas and the connectors; ours just also knows what day it is.
Automation & glue
6 toolsTools whose entire existence is evidence that you have too many other tools.
Study & learning
6 toolsEducation is the biggest slice of the note-taking market — over 43% of downloads. Students are also the people most poorly served by a list with no hours in it.
Wikis & internal docs
6 toolsWhere companies put what they know, then never read it again.
Web capture & bookmarking
6 toolsSaving things. The easiest problem in software, solved forty times.
Forms & intake
5 toolsCollecting information from other people. Useful, and almost always the start of work nobody scheduled.
Scheduling links
5 toolsTools for letting other people put things in your day. Consider carefully whether that is the goal.
Goals & accountability
5 toolsApps that try to make you do things by raising the stakes. We went the other way and it works better.
Personal CRM & people
4 toolsRemembering humans. A category that exists because calendars forgot people are the point.
Dev & issue boards
5 toolsWhere engineering work is tracked. Excellent at tickets, silent on the human holding them.
Diagramming
3 toolsBoxes and arrows as a profession.
The seven things we actually do differently
Not a feature count. Feature counts are how you end up with four sidebars. These are structural differences — things that would require the other apps to change what they are.

Every one of these is the article you were going to search for anyway. Real pricing, real strengths, and a straight answer at the bottom about which tool to actually use — including the ones where the answer isn't us.
AI planning and time blocking, answered
Answered properly first, because a page that only sells is a page nobody links to.
What is an AI planner app, and is it worth using?
An AI planner app is a day planner with an assistant built in: you tell it what you need to get done and it finds the gaps, sizes the tasks and sets up the blocks. The split that matters is who has the last word. Some AI planners reshuffle your day on their own; others propose and wait.
Fuidzy is the second kind. Ask it to block out two hours for the report tomorrow and it offers an honest slot on your timeline. Nothing moves until you say so, and the free plan includes the AI chat. Read the full AI planner comparison →
What's the best planner app? Full ranking →
It depends entirely on whether your problem is capturing or scheduling. If you forget things, you want capture: Todoist or TickTick. If you have a list you never get through, you don't have a capture problem — you have a time problem, and a longer list won't fix it.
That second problem is the one we built for. A list can hold eleven hours of work in a nine-hour day without complaint, because a list has no width. A timeline does, and ours will tell you out loud when it doesn't fit.
What is time blocking, and do I need an app for it? Best time blocking app →
Time blocking means assigning every task an actual slot in the day rather than keeping a floating list. It works because it forces you to confront how long things take. You do not need an app — a paper notebook does it — but the apps that specialise here charge accordingly: Sunsama around $20–25/month, Akiflow $34/month billed monthly.
Time blocking is Fuidzy's entire default interaction, not a premium tier. Say "block out two hours for the report tomorrow" and it finds an honest gap and offers it. It won't move your existing work to make room — an app that silently rearranges your afternoon is one you stop trusting.
What's the best productivity app if you have ADHD?
We can't make clinical claims, and anyone who does should worry you. What people consistently report helping: fewer surfaces, visible time, and no penalty for a bad day. What consistently doesn't: an app that requires a weekly review ritual to stay accurate, and streak mechanics that punish one miss.
Fuidzy is one screen, time is visible as physical width, there's no setup before first use, and nothing resets to zero to punish you. That's the design brief, not a medical opinion.
