T Tarn
For iPhone · Screen Time

Block what distracts you. Lock it in.

Tarn uses Apple Screen Time to shield distracting apps, then lets you commit to a lock so you cannot undo your blocks on impulse.

Coming soon to the App Store

🛡️ Shield any app

Block everything except the apps you choose to keep, or pick specific apps to block. Either way, a Tarn screen replaces them.

🔒 Commitment lock

Lock your settings with a cooling-off period or a password held by someone you trust. No more undoing it on a bad day.

🔐 Private by design

Everything runs on your device using Apple Screen Time. No accounts, no network requests, nothing sent anywhere.

How it works

Three steps and you are set.

  1. Grant Screen Time access and choose which apps to block
  2. Set a cooling-off period (or give a password to someone you trust)
  3. Tap Lock In. Your blocks are now committed and cannot be removed on impulse.
