Last Scroll

Last Scroll turns screen-time discipline into a school-wide contest. Pick your distractions — Instagram, TikTok, X, YouTube, Snapchat, games, whatever owns your thumb — and the app monitors combined daily use through Apple's Family Controls. Cross the 120-minute Dopamine Budget and those apps go dark until midnight. iOS does the blocking; we just set the limit. Built for students: • Dopamine Budget — a hard 120-minute daily cap on your selected distraction apps. • Productive Pass — whitelist Canvas, Google Classroom, Notion, Quizlet, Calculator, and Mail so schoolwork never counts against the budget. • School Leaderboard — every day at 9 PM your score (points = 120 − minutes used, plus a Hardcore bonus for shielding early) posts to the contest board. • Home Screen Widget — your rank in school + budget remaining at a glance. • Grade-tuned motivation — when the shield kicks in, the block screen shows a quote calibrated to your grade level. Cheat-proofing for fair contests: • If Screen Time access is revoked while monitoring is active, the day is automatically flagged Disqualified on the leaderboard. • Lifting the shield early ("emergency unlock") still resets your streak — and requires retyping a long motivational sentence. Friction is the whole point. Privacy: • Apple's Family Controls hands us opaque tokens, not names. We never see which apps you selected. • The leaderboard uses an anonymous random ID — never tied to your Apple ID, email, or name. • No analytics, no advertising, no third-party tracking. We send only { anonymous ID, today's date, score, minutes used, shielded yes/no, disqualified yes/no }. Requires iOS 17 or later.
