logi - focus app blocker

logi focus is an app blocker you switch on and off with a physical NFC key.

■ How it works
1. Pick the apps you want to block (social media, games, video)
2. Tap your logi key on your phone to start a focus session
3. If you open a blocked app during focus, a reminder screen stops you
4. Tap the key again to unlock — or it unlocks automatically when time runs out

■ Who it's for
- Anyone who keeps reaching for their phone while studying or working
- People for whom in-app blockers weren't enough — a physical key adds real friction
- Students and professionals who want less screen time

■ Your usage data stays on your device
- Screen-time analysis happens entirely on your phone. Nothing is sent to a server.
- The accessibility service only checks the name of the app in the foreground. It never reads screen content or anything you type.

■ You stay in control
- You can end a focus session anytime. This is not an unbreakable lock.
- You can turn the service off anytime in Settings → Accessibility.

You can start without an NFC key — a free mode lets you start focus manually in the app.
