App to stop procrastinating: commit to one 25-minute block

Take a tax form that's been dodged for a week as an example. At 20:00, tap Add task label, type "Tax form, section 1" and hit play on Study.

Three minutes later, the phone gets locked. Two minutes after that, it gets unlocked and a messaging app opens, and nothing stops that. That's the real limit: Pomodoro Timer doesn't block apps or websites. It keeps time and tells you when the block is over, nothing more.

What pulls attention back is the Lock Screen. Every time the phone comes out, the countdown is sitting there.

A 25-minute block, minute by minute
Clock time	What happens	What the app shows
20:00:00	Tapped play on Study	25:00, end time saved as 20:25:00
20:03:00	Locked the phone, then wandered into another app	Nothing to watch; the end time stays fixed
20:13:30	Glanced at the Lock Screen	11:30 left
20:17:45	Section 1 done early, tapped Skip	17m added to Stats, short break next

11:30 is just the saved end time minus the clock: 25 minutes minus 13 min 30 s. No counter has to stay awake for that, which is why a locked phone or a closed app loses nothing.

Why one small block beats "just start"

"Do the taxes" has no edges. "25 minutes on section 1" has an end that's easy to see. Once the clock is running, quitting feels like breaking a promise, and starting is the hard part anyway.

Set the block up so quitting costs something

Write the first physical action as the label, "open the form" rather than "taxes".
Allow Notifications when the app asks, so the end of the block reaches you with the phone locked.
Tap play on the Timer tab, lock the phone and turn it face down.
Done early? Tap Skip. Never the square stop button: it throws the block away and nothing reaches Stats.

One detail worth knowing: a skipped block keeps its minutes but doesn't count as one of the 4 blocks before the long break. The long break waits until full ones are finished, which keeps the count honest.

Over an evening and the next day, three full blocks plus one skipped block add up. Stats on This Week shows Total Time 1h 32m, Average 23m and Completed 75%. A 75% completion rate, dragged down by the skipped block, is a clearer nudge than any reminder.

Can I start with less than 25 minutes?

Yes. In Modes, tap Add Custom Mode and set focus as low as 5 minutes, in 5-minute steps up to 120. For a task avoided for weeks, starting at 10 minutes and moving up to Study once starting stops being the problem works well. The free version allows one custom mode, enough for this.

What it won't do for you

Block other apps or sites. It's a timer, not a lock.
Start the next block by itself in the free version; Auto-start Focus is Premium. Having to tap play again is a feature for some, an annoyance for others.
Stay ad-free on the free tier. Full-screen ads come after a focus block ends or when you switch modes, never while one is counting down.
Run on Apple Watch or a Mac. It's iPhone and iPad only.

There's no account to make; tap play and go. A 75% on Stats can be a little annoying to read, but it's still a more honest number than a nicer-looking one would be.

Questions and answers

Does the pomodoro technique work for procrastination?

It works on the starting part: a 25-minute block with a visible end is easier to begin than a whole task. It won't stop you opening other apps; you still have to keep the promise.

Is there a free app to stop procrastinating with a timer?

Pomodoro Timer is free to download, with ads. The timer, the Study mode, one custom mode and 7 days of stats are free; Premium removes ads and adds more modes, goals and longer history.

How do I stop procrastinating on homework with a timer?

Label the block with the first concrete step, start one 25-minute Study block and lock the phone. If 25 feels too long, make a 10-minute custom mode and work up from there.
