Screen Time Machine: Blocker

Screen Time Machine is an app blocker and screen time limit for your own phone. Block distracting apps on a schedule, cap them with a daily limit, and start a focus session whenever you need one.

You do not lose four hours in one go. You lose them fifteen minutes at a time, and by the end of the day you cannot say where they went.

This puts a system between you and the apps that take them.

You set the rules once, while you are thinking clearly. After that the rules hold on their own, so your day stops depending on catching yourself in the moment.

BLOCK APPS ON A SCHEDULE

Pick the apps, pick the hours, pick the days. Bedtime, the first hour of the morning, work blocks, homework time.
The window repeats every week without you deciding anything again.

SET A DAILY SCREEN TIME LIMIT

Give an app a daily limit and watch the meter fill as the day goes. When it is full, that app is blocked until tomorrow.
You still get your fifteen minutes. You just do not get the other three hours.

START A FOCUS SESSION

Switch it on and the apps you picked are gone until the timer runs out.
A focus timer for work, study or anything you want an uninterrupted hour of.

You can end it early if you need to. What it costs you is the receipt you would have earned.

EVERY DAY GETS SETTLED

When a day closes, the app totals what you actually spent against your cap and prints the result. Under your cap that is a receipt. Over it, a bill. You do not ask for either one.
They stack up into a roll, and the roll is the honest version of your week.

WHAT PEOPLE USE IT FOR

Blocking social media during work. A phone curfew that starts at bedtime and lifts in the morning.
A distraction blocker for studying or revision. Keeping games shut during the week.

A digital detox that does not mean deleting the apps you actually like. Screen time limits for an adult who wants them for themselves, rather than a parental control someone else set.

WHAT YOU GET FREE

One schedule, one daily limit, and unlimited focus sessions across as many apps as you want to track.
No account to make. No ads. No tracking.

WHAT PRO ADDS

Unlimited schedules and a daily limit on every app you track. $3.99 a month, or $29.99 once.
If you ever stop paying, nothing you already built is taken away.
The caps only ever apply to the next thing you add.

YOUR DATA STAYS ON YOUR PHONE

There is no server and no account.
Your apps, schedules, limits and usage figures live on your device and are never sent anywhere, because there is nowhere to send them.
We run no analytics and ship no advertising or tracking SDKs.

WHY IT NEEDS THE ACCESSIBILITY SERVICE

Screen Time Machine uses the Android Accessibility Service to detect which app has just come to the foreground.
That is the only way Android lets an app know what you opened, and it is what makes blocking possible at all.
The app that opened is checked against the rules you set, then forgotten.
It does not read screen content, does not log what you type, and records nothing you do inside other apps. Nothing it observes leaves your device.
