An app blocker for iPhone

Tasks first.Scroll later.

Atosuma is an iPhone app blocker that locks social and video apps. Focus time earns you keys. By default, each key unlocks one minute, and your apps re-lock when time is up.

How it works

Lock apps. Focus.Unlock with keys.

  1. The screen that appears when you open a locked app, asking “Open TikTok?” with a “Do something first” button.

    Lock social and video apps

    Pick the apps to lock, and they stay locked at all times. Open one and you'll see a screen with a “Do something first” button. The free plan locks one app; Pro lets you lock more.

  2. Focus time in progress: the task name, a timer, the keys “Earned so far,” and an “End early” button.

    Earn keys in focus time

    Pick a task like Study or Work and start focus time. Both earn 20 keys an hour. End early and you still get keys for the time you put in.

  3. The Unlock apps screen: packs from 1 to 20 minutes, and a receipt showing the chosen pack, the total keys, and the rate “1 min = 1 key.”

    Pick how many minutes

    Choose packs of 1, 3, 5 minutes or more, then press and hold to unlock. By default, one key buys one minute. Apps re-lock when time runs out, and if you re-lock early, your unused keys come back.
