About

Radical Timer

Read full description

Radical Timer is a focus timer that actually holds you to it. Set a session from 5 minutes to 8 hours. You get a short grace period to lock your phone and put it down. After that the rule is simple: pick up the unlocked phone or leave the app, and the timer fails. No honour system. No "are you sure?" dialog. The phone has to stay put. HOW IT WORKS โ€ข Set your session โ€” 5 minutes to 8 hours โ€ข Use the grace period to lock your phone and set it aside โ€ข Motion detection watches for the phone being picked up โ€ข Quit the app while a timer runs and the session fails โ€ข Finish it and your phone tells you KARMA Every session you abandon costs a karma point. Lose all ten and your timer options are limited until you earn one back by completing a full hour. It is a small price that turns quitting into an actual decision instead of a reflex. LOCK SCREEN A Live Activity keeps the countdown on your Lock Screen, so you can see the time left without unlocking anything. FOR PARENTS Turn on Parental Control and each session shows a random emoji pair. Ask your child which emojis appeared โ€” if they changed, the timer was restarted. CALLS STILL WORK This is not a lockdown app. Your phone stays a phone. Nothing is blocked, nothing is taken away. You simply have a reason not to reach for it. PRIVACY No account. No tracking. No analytics. Nothing leaves your device. Settings and karma sync through your own iCloud, and that is all. PRICING Seven days free, then a one-time purchase. No subscription, ever.
