StayOff vs MathBlocker

SnappOff is a digital wellbeing app that helps users break unhealthy screen habits by locking selected apps for custom durations. Once locked, apps stay inaccessible until the lock period expires — no bypassing, no exceptions. Users can set one-time locks, recurring schedules by day and time, and track their usage through built-in analytics. SnappOff is designed for anyone who wants a firm, reliable way to reduce time spent on social media, games, or any distracting app.

MathBlocker puts a math problem between you and the apps you open too much. You pick the apps you want blocked. When you try to open one after your time's up, a math question shows up instead. You answer it, you get a few minutes back. You don't, the app stays closed. The questions are real. They come from the same problem sets people use to study for the SAT, ACT, AMC, and AIME. You can set the difficulty. Easy questions if you just want a speed bump. Harder ones if you actually want to stop scrolling. Features - Block any app or category — social, video, games, news, browsers - Pick your difficulty, from warmup arithmetic to competition-level - Choose your problem set: SAT, ACT, AMC, AIME, Putnam, or general practice - Earn time back per problem solved (you set how much) - Daily, weekly, and per-app limits - Schedule blocks by time of day (bedtime, study hours, work hours) - Dashboard with usage broken down by app, hour, and day - Custom block screen so it actually feels like a stop sign - Works with Family Sharing if you're setting it up for someone younger A few ways people use it: blocking social apps during work hours. Locking everything after 10pm with hard math. Pairing it with actual SAT prep so the time you would've spent scrolling becomes practice instead. Everything stays on your phone. No account, no login, no data sent anywhere. iOS 16 and up. iPhone only.
