About this app

Tacet turns exercise into screen time. Do squats or pushups — or hit your daily step goal — and earn minutes to use your favorite apps. When your time runs out, apps lock again until you move.

HOW IT WORKS

1. Choose which apps to lock behind exercise
2. Pick an exercise — squats are free, pushups and step goals are premium
3. Complete reps to earn screen time
4. Start your session when you're ready — a countdown tracks your remaining minutes
5. When time runs out, apps lock again. Earn more to keep going.

Choose whether to reset your earned time daily or bank it across days.

CAMERA-COUNTED REPS

Prop your phone up. The front camera uses on-device pose detection to count your reps in real time. No cloud processing. No video saved. No data leaves your phone. If you did the rep, it counts. If you didn't, it won't.

STEP GOAL (PREMIUM)

Hit your daily step goal and earn bonus screen time. Steps sync from Health Connect — no need to open the app while walking. Configure your goal and reward in Settings.

DAILY AND WEEKLY CHALLENGES

A new challenge every day. Hit the target, earn bonus minutes. Weekly challenges for premium users add variety and keep it interesting. Challenges rotate from a pool of templates with no repetition within 7 days. Daily streaks keep you moving.

BLOCKING THAT ACTUALLY WORKS

When a locked app is opened, Tacet shields it instantly and shows how to earn more time. No VPN. No workarounds. When an app is locked, it's locked.

ACCESSIBILITY SERVICE

Tacet uses the Android AccessibilityService API to detect the moment a locked app is opened, so the shield appears instantly and blocking keeps working after the system kills background processes. Tacet only receives window-state events — which app came to the foreground. It cannot and does not read, collect, store, or transmit your screen content, text, or keystrokes. The permission is optional, requested only with your explicit consent, and can be revoked at any time in Android Settings > Accessibility.

SESSION MODE

You control when your earned time starts. Earn 30 minutes of screen time, then tap Start when you're ready. Tap Stop when you're done — remaining time is saved.

If you forget to stop, a failsafe re-locks your apps when your balance hits zero.

The free tier is genuinely usable: squats, unlimited locked apps, daily challenges, and full session mode.

PREMIUM

Unlock pushups and step-goal earning, plus weekly challenges. $9.99/month or $39.99/year with a 7-day free trial.

PRIVACY

No accounts. No servers required. Your exercise and session data stays on your device. Camera processing happens entirely on-device — no video is recorded or transmitted. Accessibility events are used only to identify which app is in the foreground — your screen content is never read, stored, or transmitted.
