Tired of opening the same apps on autopilot? Chess Lock is an app blocker and screen-time tool that puts chess between you and your distractions. Instead of a PIN you tap without thinking, you unlock with a sequence of chess moves — and when you hit your daily limit, you solve a chess puzzle to keep going. Less screen time. A sharper mind.

🔒 APP LOCK, REINVENTED
• Chess Move Password — lock any app behind a secret sequence of moves only you know
• Puzzle Gate — hit your usage limit and solve a chess puzzle to continue
• Brick Mode — a high-friction lock: master a chess opening to earn access
• Biometric unlock — fingerprint or face, whenever you want it

⏳ BEAT SCREEN TIME & STAY FOCUSED
• Focus Sessions — block distracting apps with non-negotiable, Pomodoro-style timers
• Strict Mode — stops you lowering your own limits during focus hours
• Usage Insights — see reclaimed time, streaks, and your focus habits
• Per-app limits — protect only the apps that steal your time

🛡️ PRIVACY & DIGITAL WELLBEING
• Secure Vault — encrypt and hide private photos and videos
• Stealth options — Icon Swap (disguise as Calculator/Weather) and Fake Crash Mode
• Local-first — your data stays on your device. No accounts. No servers.

♟️ WHY CHESS?
A lock protects nothing if it's mindless. Chess Lock replaces lazy taps with the elegance of chess — so your apps are guarded by the one thing no one can copy: your own mind. Every unlock is a rep. Every puzzle makes you a little sharper.

Whether you're fighting phone addiction, building deep-focus study habits, protecting private photos, or you just want a screen-time blocker that actually makes you better — Chess Lock turns self-control into a game you win.
