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.

Voyage turns a study session into a flight. For students, by students. Pick a real route on the globe. The flight time is your study time. SFO to LAX is 1 hour 25 minutes. SFO to JFK is 5 hours 30. Pick a seat, write down up to three things to work on, and tear your boarding pass to take off. Turn on Airplane Mode and Voyage blocks the apps you pick, from takeoff until you land. It uses Apple's Screen Time, so your music and the map keep working. The list of apps stays on your phone. While you study you can look out the window, listen to the cabin, or follow your plane on the map. If you leave the app for more than 30 seconds, your flight stops early. It's a lot easier to stay when there's a plane to land. No destination in mind? Open skies takes off for 25 minutes with nowhere planned. Tap to fly it yourself, let go and the autopilot takes over, and it lands you at a real airport nearby. When you land, customs asks you three quick questions out loud about what you studied. It runs on your iPhone, and you can turn it off. Then you get a passport stamp and a logbook entry. You can replay any trip on the map and share it. Long routes have real connections with a layover between legs. Widgets and a Live Activity show your flight on the Home Screen and Lock Screen. I'm Patrick. I study electrical engineering at UCSB and I fly a lot. I love it. I built Voyage because I wanted studying to feel more like that. It's free. No ads, no subscription, no account. Your history stays on your phone. The code is open source at https://github.com/machmoon/Voyage. If something breaks or you want a route added, open an issue there.
