About

Crux

Crux blocks the apps that steal your time — so you can actually focus. Set a session, pick the apps to block, and put your phone down. Crux uses Apple's Screen Time technology to enforce the block system-wide, even if you close the app. FOCUS SESSIONS Block any app for as long as you need. Crux holds the block until the session ends — no cheating. SCHEDULED SESSIONS Set recurring blocks in advance. Your protection runs automatically, even if you never open the app. NIGHT MODE Block apps during your sleep window. Wake up to how many times you reached for your phone, how long you were on it, and which apps kept you up. INSIGHTS See where your day actually went — hour by hour, and which apps took it. Crux marks the hours it protected for you, and tells you how today compares with your usual pace. HOME SCREEN WIDGET See what's coming without opening the app — your next session, tonight's sleep window, and a live countdown while a block is running. STREAKS & STATS See your focus streak and total time saved grow over time. YOUR DATA STAYS ON YOUR PHONE Crux reads your Screen Time data inside Apple's sandbox, and it never leaves your device. We never see which apps you use, or which ones you block. No gimmicks. No fake willpower tricks. Just a hard block on the apps that shouldn't have your attention.
