The blocker you cannot argue with

Lock the app. Keep the habit.

A friend holds the password, so you cannot unlock alone. Deleting the app does not reset it. Focus that actually sticks.

Three ways to lock

Pick the mode that fits the moment. Every one is hard to cheat, by design.

Why Atomic Blocker

What you can count on

You never hold the password

A friend sets it and keeps it. You cannot peek, guess, or talk yourself into unlocking.

Reinstall-proof

Deleting and reinstalling the app does not clear an active block. The lock lives beyond the install.

Built on habits

Every block you keep feeds a streak and an identity, in the spirit of Atomic Habits. Small locks, compounding wins.

Private by default

Your friend arms a block. They do not see your data or your screens. The lock is the only thing shared.

Hand a friend the password. Get your focus back.

Three lock modes, one habit loop. Free on iOS and Android.

Frequently asked

How does the friend-lock work?+

A friend sets and holds the password and arms a block for a set number of hours. You never see the password, so you cannot unlock on your own.

What if I delete the app to get around a block?+

It does not work. An active block is reinstall-proof: it is backed by the server and an OS backstop, so deleting and reinstalling does not reset it.

What are the three lock modes?+

A timer or schedule block, a friend-armed block for X hours, and a detox to-do gate that keeps apps locked until today's habits are done.

Can my friend see my data?+

No. A friend only arms and holds the lock. They do not see your screens, messages, or usage.

Is it free?+

Yes, free on iOS and Android at launch.

What languages is it in?+

The app ships in English, Spanish, French, and German.
