Your feed was built by thousands of engineers to be impossible to leave. Uglify makes it boring. Pick the apps to watch. You get 15 minutes a day in full color, shared across them. Once they're spent, those apps get worse in three steps: 1) Flat Gray. Color is gone. Your feed looks like a newspaper from 1987. 2) Dull Dimmed. The screen darkens, like watching through fog. 3) Nuclear. Colors invert. Genuinely unpleasant. That's the point. » Works with TikTok, Instagram, YouTube, X, Facebook, Snapchat, Reddit, Threads and Pinterest » Your minutes in the Dynamic Island or on the Lock Screen » Optional mute when the filters kick in » No streaks.

Choose the apps or app categories you want to limit, start a lock, and CalcGate will require you to solve math challenges before access can be restored early.
