About
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 a summary of last night's pickups and screen time.
STREAKS & STATS
See your focus streak and total time saved grow over time.
No gimmicks. No fake willpower tricks. Just a hard block on the apps that shouldn't have your attention.

What's New in Crux
1.0.1
June 29, 2026
This update makes Crux easier to manage: • Pause and resume scheduled sessions without deleting them — great for weekends or days off. • Edit your name anytime from Settings. • Night Mode now asks for confirmation before turning off, so you don't disable it by accident. Thanks for using Crux. More focus, fewer distractions.
