You know you spend too much time on your phone. You have probably tried to quit cold turkey, blocked everything, lasted two days, and gave up. Curb is built for what actually works. Instead of slamming your screen time to zero, Curb sets a daily limit based on how much you really use your phone right now, then lowers it a little every day. The drop is small enough that you barely notice it, but it adds up. Over a few weeks you end up using your phone far less, without the whiplash. How it works: Curb watches your real usage for two days to learn your starting point, then builds a gentle downward curve toward the goal you set. Hit your limit and Curb steps in with a full-screen reminder and one real suggestion for something to do instead, drawn from your own interests. Not a lecture, just a nudge and an idea. Have a heavy day? Curb pauses the curve instead of punishing you. The goal is a habit you keep, not a streak you break. What makes Curb different: Suggestions that fit you. Tell Curb what you are into and it suggests real things to do when you put the phone down, including places near you. Honest, not preachy. No shame, no scary graphs, no pretending one bad day ruins everything. Private by design. Everything happens on your device. Curb has no account, no servers, and collects nothing about you. Your usage never leaves your phone. Built to fade out. The point is not to use Curb forever. It is to need it less over time. Curb is free. No subscriptions, no ads, no catch. This is your phone and your call. Curb just makes the better choice a little easier.
