Block Instagram, TikTok, Reddit — no friction, no jailbreak, no other app needed.
Solo Lock is a self-commitment device for breaking the social-media scroll. Pick the apps that eat your time, set a focus block, and hand the metaphorical key to a "lockmaster" that will not negotiate. No friend required.
WHO IT'S FOR
• Students who can't stop checking TikTok during homework.
• Parents who want a serious tool — not a cute timer — to keep their kids off Instagram during study time.
• Anyone whose first thought in the morning is "just five minutes of Reddit".
TWO LOCKMASTERS (both free)
• AI Judge — an algorithmic, fully on-device judge that does not negotiate. No early unlock, period.
• Random Delay — if you want out early, wait 15 minutes AND type a 200-word essay explaining why this is so urgent. Most of the time, by paragraph two, it isn't worth it.
HOW THE LOCK WORKS
Once you "hand over the key", Solo Lock shields the apps you picked using iOS Screen Time (Family Controls). Open a blocked app during a session and you get the Solo Lock screen — not the app. The timer counts down, the lockmaster decides whether you can end early, and a 5-second emergency hold reveals a friction screen instead of an instant exit. The shield lifts automatically when the timer ends.
THE AI JUDGE IS FULLY ON-DEVICE
The judge replies via a deterministic combinatorial algorithm running entirely on your phone. No LLM. No network. No data sent anywhere. Capable of producing billions of unique replies in a notarial, dry-humorous voice.
ANTI-FEATURES (THINGS WE REFUSE TO DO)
• No streak shaming. No "longest session" pride wall.
• No "your friends focused longer" social comparison.
• No paid white-noise / focus music upsell. That's other apps.
• No paywall on your own history.
• No mockery for emergency unlocks.

v1.3 — Real Screen Time shielding is here.
• Block apps for real. Solo Lock now uses iOS Screen Time (Family Controls) to shield the apps you choose for the whole session. Open a blocked app mid-session and you get the lock screen — not the app.
• The shield lifts automatically the moment your timer ends, even if you force-quit Solo Lock.
• Both lockmasters — AI Judge and Random Delay — are now free.
• Free tier: shield up to 3 apps, sessions up to 4 hours. Pro removes both limits.
• Cleaner paywall, lifetime up front.
