Set your execution window
Pick the hours you will actually work today. That range is your container. Everything happens inside it. Nothing rolls over to tomorrow.
Deyleo · Daily Execution System
Your day has one window. Use it.
One execution window. Five focused blocks. Unplanned time tracked live. Now available on Google Play.
You plan your day.
You feel productive.
Then nothing actually gets done.
Time is already limited. You just ignore it.
Deyleo is not a productivity app. It is a constraint system. You get one fixed window to work inside. Five blocks to fill it. When the day starts, the clock runs. Time outside a block becomes visible. You cannot hide from it.
Deyleo v2.0 is now live on Google Play. Web version also available.

Interface
See Deyleo in motion.
Plan. Execute. See the day unfold.
Principle
The limit is the point.
Most systems fail because they have no ceiling.
You can always add one more task. One more list. One more project.
Deyleo doesn't work that way.
One fixed window. Five blocks. That is the entire system.
The constraint is not a restriction.
It is the mechanism that forces every real decision about your day.
If it's not in a block, it didn't happen.
You don't need a better plan.
You need a deadline.
Why most productivity systems fail
Unlimited lists remove urgency. That is the problem.
Unlimited task lists create unlimited procrastination.
No ceiling means no real decisions.
No real-time accountability means drift stays invisible.
You keep planning. You keep delaying. You assume tomorrow will be different.
Deyleo removes that illusion.
Five blocks. One window. No backlog to disappear into.
If everything is important, nothing is.
This is not a to-do app.
It is a constraint system.
The System
Three steps. One discipline.
Plan up to 5 time blocks
Structure your day in labelled, timed blocks. You cannot add a sixth. The limit forces the decision before your window even opens.
Execute. Face the clock.
Unplanned time accumulates in real time. Gaps are shown, not hidden. End-of-day debrief closes the loop. The record is permanent.
Key Feature
Your day is being counted. Right now.
Deyleo doesn't just track what you planned. It tracks what actually happened.
Time inside a block is structured. Time outside a block becomes unplanned. Calculated from real elapsed time, not intention.
Future plans don't count. Only elapsed time matters.
Example
You plan a block from 15:00 to 18:00. It is currently 13:00.
That block does not reduce your unplanned time yet.
At 15:00, when the block begins, it starts counting as structured.
Deyleo reflects reality. Not intention.
Inside a block
Structured time. Counts toward your day.
Outside a block (past)
Unplanned time. Visible. Accumulating.
Future blocks
Not counted yet. The clock decides.
Every hour unaccounted for
is shown. Not forgiven.
Features
Designed to create pressure. Not motivation.
Not gamification. Not streaks for dopamine. Structural pressure to use your time. Or face the record of not doing so.
Questions
Before you commit.
Is this a one-task-per-day app?
No. You can plan your whole day using up to 5 blocks. Each block can represent a different project or focus area. The limit stops the list from growing endlessly. It does not reduce your day to a single thing.
What if I have more than 5 important things?
Then you have too many important things. Five blocks is enough to structure a full day. The cap forces you to decide what actually belongs in today. That decision is the entire point. Most systems let you defer it indefinitely. Deyleo does not.
Why only 5 blocks?
Because unlimited lists are why most productivity systems fail. The cap is the mechanism. It forces real prioritisation. You cannot defer the hard decisions by adding more. Your day is finite. Your task list should reflect that.
What exactly is "unplanned time"?
Unplanned time is time that has already passed today outside a planned block. If it is 2pm and you had no block between 10am and 2pm, those four hours are unplanned. Calculated from real elapsed time, not prediction. Future blocks do not reduce it retroactively.
Why doesn't a future block reduce unplanned time now?
Because it hasn't happened yet. Deyleo reflects reality, not intention. Planning to work at 15:00 does not make your morning more productive. Only elapsed time inside a block counts as structured. The system rewards execution, not planning.
Is this just a Pomodoro timer?
No. Pomodoros break your day into small repeating intervals. Deyleo works at the scale of the whole day. You commit to a fixed execution window, structure it in up to five blocks, and account for every hour inside it. The point is day-level discipline, not 25-minute cycles.
How is this different from a to-do app?
To-do apps are infinite by design. You can always add another task, list, or project. Deyleo is the opposite. It shows you a finite container and asks what fits. Unplanned time is tracked and surfaced, not hidden behind an endless backlog.
What does Focus Mode actually do?
Focus Mode enables Do Not Disturb on your device and silences notifications for the session. Choose 30 minutes, 60 minutes, or until your window closes. Silence enforced by the system. Not willpower.
Is there a mobile app?
Yes. Deyleo is available now on Android via Google Play. An iOS app is also in development. The web version works on all mobile browsers in the meantime, including Focus Mode with Do Not Disturb.
What does it cost?
Pricing is being finalised. Download it now on Google Play and start using it while it's free.
Who is this built for?
Operators, founders, and anyone whose output depends on deep work rather than reactive busy-work. If you want to stop overplanning and start executing with real daily structure, this is for you. If your calendar is already full of back-to-back meetings, this is not.
Begin
One window.
Five blocks.
No more excuses.
Deyleo is live on Google Play. Your day is finite. Act like it.
