I'm 17 and built ScreenWise because I was losing hours to my phone and Apple's Screen Time felt clunky. So I learned Swift and built something better. Shows daily/weekly app usage, set your own goals, tracks streaks, enforces limits, blocks screen-free time. All data stays on device via Apple's Screen Time API. Free. No ads. No subscription. No account. No data collection. Took 6 Apple rejections to get here — but it's live!
