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. No shame. No guilt.

Read full description

CalcGate is a screen time control app designed for people who want to break the habit of opening distracting apps without thinking. Have you ever opened social media “just for a minute,” only to lose track of time? Do you find yourself checking your phone when you should be studying, working, or focusing? Do app limits feel too easy to ignore or turn off? CalcGate adds a simple but effective moment of friction before you can reopen restricted apps. 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. Unlike blockers that can be dismissed instantly, CalcGate is designed to make you pause and ask yourself: “Do I really want to open this app right now?” To unlock early, every math problem must be answered correctly.

CalcGate is useful for study sessions, deep work, productivity, reading, reducing late-night scrolling, managing screen time, and building healthier digital routines. Key features: ・Restrict selected apps or app categories ・Start instant locks anytime ・Create recurring daily lock schedules ・Unlock early by solving math challenges ・Customize challenge difficulty and question count ・Reset progress after incorrect answers CalcGate is not about completely avoiding your phone. It is about using your phone more intentionally.
