Before you open
One reply.
A clear stopping point.
Keep the apps you need. Add a moment to choose why you are opening them. No purpose right now? Choose “Not now” and leave the app closed.
How it works
Try it with one distracting app.
Give it a purpose
Open your selected app, then tap the notification to return to What For?. Write what you came to do and choose 5, 10, 15 or 30 minutes.
Go back with a stopping point
Open your selected app from the Home Screen. It is restricted again when your time ends. Reflect on whether you did what you intended.
Your first guided session is ad-free. Later unlocks use a rewarded-ad step. Notifications help you return to What For?; you can also open it yourself.
Setup help and common questions Your data
Your written purposes stay on your device.
No account is needed. What For? does not read messages, posts or searches inside your apps. The main app uses AdMob for ads, and Firebase for usage analytics and crash reports. You can turn analytics and crash collection off in Settings.
Make it yours
A different rule for each app.
Set the time you need
Choose a purpose and a short time limit for a reply, a search or a planned break.
Adjust your boundaries
Change purpose choices, default times, daily limits and cooldowns for each selected app.
