Studying doesn't fail because you're lazy. It fails because Instagram is one swipe away, and willpower is not a strategy. OnLock is the block you can't talk yourself out of. When a session starts, OnLock locks your distractions at the operating system level using Apple's Family Controls. No "5 more minutes." No uninstall trick. The shield holds until you finish. But blocking is the easy part. The hard part is proving the work was real. Before any session counts toward your streak, OnLock's AI reviews a photo of what you did. No proof, no credit. THE SHIELD • Un-bypassable OS-level enforcement built on Apple's Family Controls • Locks the apps that derail you: social, games, browsers, anything • Holds through restarts, app deletion, and panic uninstalls • Schedule recurring blocks for the hours you always slip AI PROOF • Submit a photo of your notes, work, or finished problem set • AI verifies the session was genuine study before your streak counts • Catches the "I just sat there" sessions you'd rather forget • Builds a streak you actually earned THE INTERVENTION • A quiet pause before every session to ask if this is really study time • Journal your intent so distraction has to argue with your own words • Reflect after to see what is actually working THE WHY ON A TIMER • Plot your exams on a real countdown • Every session lands against the clock • See what each lost hour costs you FOCUS INTELLIGENCE • Learns your peak hours, worst blockers, and patterns • Tells you when to study and when to stop pretending • Your data, your insight, never shared ALWAYS ON • Home screen widgets in three sizes • Lock screen complications for glanceable streaks • Quick Study: one tap and you're locked in THE AESTHETIC A calm, editorial interface designed to feel nothing like the apps it replaces. No infinite scroll. No screaming notifications. No dopamine arcade. Just focus. PRIVACY • Screen time data stays on your device • Built on Apple's native Family Controls and Screen Time APIs • Photos for AI proof are reviewed and discarded • No tracking, no sale, no leak FREE Every feature above is included, free. No subscription, no upsells, no locked tools. Stop trying harder. Start being unable. OnLock. The focus you can't undo.
