A list that only grows
You add more than you can do, and the list never gets shorter.
The to-do app that starts from your time
Plan only what fits.
Most to-do lists only grow. Plenzu adds up how long your tasks take and sets it against the hours you really have. So you plan a day you can finish, and end it calm.

Sound familiar?
A to-do list happily takes a fortieth task. Your day does not get any longer.
Every evening, the same leftovers
Unfinished tasks roll over to tomorrow, and the day after, and bring guilt along.
Busy all day, nothing finished
You jump between tasks because nothing tells you what fits today.
Plenzu works the other way around: it starts from your time, not from your list.
How it works
Three steps to a day that fits
- 1
Add tasks with a duration
Type “Call the plumber 15m tomorrow @home” and Plenzu puts it in the right place, with its duration.
- 2
See whether your day fits
The time bar adds up what you planned and sets it against the hours you have, with a buffer for the unexpected.
- 3
Start each morning calm
A short daily start asks what to do with yesterday’s leftovers: today, another day, or let go.
Try it
Does your day fit?

Plan your real dayFeatures
Built to keep your days doable
Know at a glance whether your day fits
Give tasks a duration and the time bar shows how much you planned against the hours you have. Green while it fits, amber when it really is too much. Never red.
- A buffer for the unexpected, 15% by default
- Your own hours per weekday, and per date when a day is different
- Tasks without a duration are counted separately, not guessed
A calm start, without guilt
No red “overdue” list. Each morning Plenzu shows what was carried over, and you decide in a few taps: do it today, move it, or let it go. Letting go is a decision too.
- “Carried over” instead of “overdue”
- After three moves, Plenzu asks whether it is still worth doing
- Split a big task into subtasks that do fit
Spread your week before it fills up
The week planner shows every day with its own time bar. Drag tasks from a busy day to a quiet one and see the week balance out.
- Unplanned tasks wait in a drawer next to the week
- Change the hours for one day without touching the rest
- Plan exact times in the day planner when you want to
Workspaces with a status and an optional timeline
Keep bigger plans next to your daily work. Each workspace has a status, from idea to done. Give it dates and a timeline with milestones when it is a real project, and it tells you honestly when it falls behind.
- Idea, Active, Waiting and Done, always with a word and an icon
- Tasks and milestones on a week, month or quarter timeline
- “Starts after” links tasks that wait on each other

Calm by design
A to-do app that does not make you feel behind
Carried over, not overdue.
Unfinished is not failed. Tomorrow is a new plan.
Let go. That’s a decision too.
Some tasks are not worth doing anymore. Plenzu lets you drop them without guilt.
Amber, never red.
Plenzu warns you only when a day is really too full, and offers a way out.

Questions
What is Plenzu?
Plenzu is a to-do app and day planner. You give tasks a duration, and Plenzu shows whether they fit the hours you have today and this week. It also has workspaces with a status and a timeline.
How is Plenzu different from Todoist or TickTick?
Those apps keep a list of everything you want to do. Plenzu also knows how much time you have, and adds up how long your tasks take. So you see before your day starts whether your plan fits, instead of finding out in the evening.
Is Plenzu free?
Yes. Everything you see now is free. Later there will be a Pro plan with extras for €39 a year, and the free plan stays.
Do I have to give every task a duration?
No. Tasks without a duration simply are not counted in the time bar, and Plenzu shows how many there are. A duration takes one word when you add a task, such as “30m” or “1h”.
Does Plenzu work on my phone?
Yes. Plenzu works in every modern browser, on a phone, tablet or computer. You can add it to your home screen as an app, and your last loaded day stays readable without internet.
Where is my data stored, and can I take it with me?
Plenzu runs on its own server in the EU. You can download all your tasks and workspaces as JSON or CSV at any time, and delete your account with everything in it.
Is Plenzu available in Dutch?
Yes. Plenzu speaks English and Dutch. You can switch at any time in the settings.
