Description by Idan Rachmani Written by the developer, not by AppBrain. Click to read.
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.
