Curbox

A screen-time and app blocker for Android that gives you your attention back without taking your data. You pick the apps, sites, and short-form feeds to watch, and Curbox shows a pause screen when you hit a limit. It can block a whole app or just one feature like Reels or Shorts, run focus sessions, and add a bit of friction (a cooldown, a QR scan, or typing out why you want to open something) before you can keep scrolling. It is open source under the GPL v3, with no accounts.
