The cross-device problem
Most people plan on a laptop and check the plan on a phone. If your time blocking app only lives on one, the plan drifts out of date. So the real question isn't 'which app is best' but 'where do I actually look at my day'.
Your options
- Calendar apps (Apple Calendar, Google Calendar) work everywhere and can hold blocks, but they're built for events, not tasks.
- Native planner apps feel fast and integrate with the operating system, but are usually tied to one platform or priced per platform.
- Browser-based planners run on any device with a browser, so the plan is the same on Mac, Windows, iPhone and Android.
How the options compare
| Approach | Works on | Strength | Trade-off |
|---|---|---|---|
| Calendar app | All major platforms | Familiar, syncs | Tasks and events are mixed up |
| Native planner | Usually one or two platforms | Smooth, system integration | Plan can be stuck on one device |
| Browser planner | Anything with a browser | Same plan everywhere, no install | Needs a connection for some features |
What to check
- Does it sync reliably between the devices you use?
- Can you add a task in a few seconds on a phone?
- Does it support dragging blocks, not just typing times?
- What's the free tier, and does it have limits you'll hit this week?
- Can you export or leave if you change your mind?
Time blocking in Apple Calendar or Google Calendar
- Create a calendar called 'Blocks' so it can be shown or hidden.
- Add each block as an event with a clear name, like 'Deep work: report'.
- Use colour for block types: focus, admin, recovery.
- Turn on a notification for the start of each focus block.
- Drag events to reschedule. Review each evening.
It works, but tasks live elsewhere, so you copy items between the list and the calendar by hand. Planners that treat a task and its time slot as one thing remove that step.
A cross-device routine that sticks
- Plan on the device you use for deep work, usually a laptop.
- Glance at the plan on your phone, and only edit there for small moves.
- Pick one place for capture and always use it.
- Do a two-minute evening review on whichever device is closest.
Planning this on a real timeline is easier than reading about it.

- Check you're signed in to the same account on every device.
- Reload the page or app after a long gap offline.
- Avoid editing the same block on two devices at once.
- If a plan looks wrong, trust the device that was edited last and re-check the other.
What to look for on a phone specifically
- A layout that works with one thumb, not a shrunken desktop screen.
- Fast capture: one tap to add, one line to type.
- Readable timelines at small sizes: you should still be able to see the shape of the day.
- Reasonable behaviour with a patchy connection.
Which setup suits you
| You mostly... | Consider |
|---|---|
| Work on one computer and rarely plan on a phone | A native desktop planner or a browser planner |
| Switch between Mac, Windows and phone | A browser-based planner, so the plan is identical everywhere |
| Live in your calendar already | Time block inside your calendar, and add a task planner if lists get unwieldy |
| Want reminders at your desk | A desktop app with system-tray notifications |
None of these is wrong. The best setup is whichever one you'll open without being asked.
Where Fuidzy runs
Fuidzy's planner runs in the browser, so it works the same on Mac, Windows, iPhone and Android with no install. There's also a Windows desktop app with a global quick-capture hotkey and a small companion that reminds you from your desktop. The planner is free, with an optional Supporter plan.
