Most digital detox apps want you to sign a contract with yourself: no phone for the next X minutes, no more than Z minutes in app Y. A few of them take your money when you break it. DetoxDroid works the other way round. It strips the attention-grabbing tricks out of the phone, so that a calm phone is what you get when you do nothing at all. Nothing to start, no session to survive. The protection is simply on, and you pause it on purpose when you actually need something. Use your phone. Don't let your phone use you. HOW IT WORKS You sort your apps and websites into groups. A group says when it counts: always, at night, weekdays from nine to five. It says how much time its apps and websites get together, per day or per clock hour. And it says what happens then: a short wait before each open, gray, a break when you scroll too long, a lock.

Notices when you are stuck in an endless feed, and counts the short videos you swipe through on Reels, Shorts and TikTok. After the break, that feed stays locked for a cooldown. * Wait and lock. A distracting app can make you wait a few seconds before it opens, s
