Studying alone is why you stop. Study Tracker turns it into a duel with a friend. TIME IT Start the timer when you sit down. It keeps running if you lock your phone, close the app, or restart it β€” your session is anchored to a start time, not to the app staying open. A Live Activity keeps the count on your Lock Screen and in the Dynamic Island. Forgot to start it? Add the session manually. DUEL A FRIEND Challenge anyone on your friends list. Each round runs seven days from the day they accept. Win a point for every day you study more than they do, three for winning the week. Your existing sessions count automatically β€” nothing is logged twice. SEE IT HONESTLY Hours per day, cumulative by hour, where your time actually went by subject. A daily goal, a streak that only counts days you hit it, and a running week total. Overlay a friend's data on your own charts to see the gap. TALK ABOUT IT Comment on each other's sessions. See when a friend is studying right now. Get a notification when they log time or reply to you. MADE FOR REAL COURSEWORK Track subjects separately. Eight accent colours, and the app icon changes to match. EVERYWHERE The web app and the iPhone app are the same account and the same data, live in both. PRIVATE BY DEFAULT You choose whether your progress is private, visible to friends, or public. Report or block anyone. Delete your account and everything in it from inside the app, whenever you want. Free. No ads. No tracking.
