What Todoist is genuinely great at
Typing "gym tomorrow 6pm every weekday" and having it simply understood. Todoist's parser is excellent, it's on every platform, it syncs instantly, and the free tier is generous. As a place to put things so you stop carrying them in your head, it's close to perfect.
Pro is $5 a month ($60 a year), which is fair for what it does.
Where it falls down
Here's the thing nobody says about to-do apps: a list is one-dimensional. Each item takes up one line, whether it's a five-minute email or a six-hour rewrite. So a list of fourteen items looks exactly as achievable as a list of fourteen items that happens to contain thirty hours of work.
That's why people end most days having "not got through the list" — not because they're lazy, but because the list never told them it was impossible. Todoist can't fix this without becoming a different shape of app.
How Fuidzy is different
Every task has a length you can see and drag. Thirty hours of work will not fit in a nine-hour day and the timeline shows you that before the day starts, not at 6pm when you've failed. A lane holds one thing at a time, so the plan can't quietly lie about what fits.
We're honestly worse than Todoist at capture — their parser is better than ours. Many people use both: capture in Todoist, plan the day here.
Use Todoist if you forget things and need a fast, reliable inbox for your life. It's excellent at that.
Use Fuidzy if you already have a list and the trouble is that it never fits into real days.
