LockIn: Focus App Blocker

About this app

LockIn is a strict app blocker for people who want real focus without complicated routines, streaks, subscriptions, ads, or a paid app purchase.

No subscriptions. No ads. No one-time purchase to use the app. Keep your promise and LockIn stays free. The only paid action is early unlock: if you choose to end an active session before the time you set, Google Play Billing charges the unlock fee.

Choose the distracting apps you want to block, choose any end time from 5 minutes to 24 hours, then long-press to start. During an active session, LockIn blocks the apps you selected and sends you back before you lose more time.

Use LockIn to:
- Block distracting apps during work, study, reading, or deep focus
- Reduce social media scrolling
- Create focused phone-free sessions
- Add real commitment to your screen time goals
- Make app blocking simple, fast, and intentional

Key features:
- App blocker for selected apps
- Presets or any end time from 5 minutes to 24 hours
- Long-press commitment start
- Early unlock through Google Play Billing
- Optional recent app usage ranking
- Simple app picker with search and suggestions
- No account required
- No subscriptions
- No ads
- No paid app purchase to use the app

LockIn is intentionally simple. There are no feeds, no badges to chase, no social dashboard, and no complicated setup. Pick apps. Lock in. Stay focused.

Optional Usage Access:
If you enable Usage Access, LockIn ranks launchable apps by recent on-device usage so the app picker starts with apps you actually open often. Usage statistics stay on your device and are not sent to a developer server.

Accessibility disclosure:
LockIn uses Android Accessibility only to detect the app currently in front during an active focus session and show a blocking screen when it matches an app you selected. LockIn does not read typed text, collect screen contents, perform gestures, automate other apps, or send your selected app list to a developer server.

Purchases:
LockIn has no subscription, no ads, and no one-time purchase required to use the app. Early unlock purchases are processed by Google Play Billing. You are only charged if you choose to unlock a session early.

Privacy:
Your selected app list and session state stay on your device. LockIn does not require an account and does not upload your focus sessions to a developer-operated server.

LockIn is for adults who want a stronger way to block distracting apps, protect focus time, and reduce mindless phone use.
