Not for everyone. A lock app and a social feed, for people who actually want to change. 1% locks the apps you choose — and turns the time you stayed away into a record you can see. ■ Put the phone down · Timer — decide how long you're focusing, then lock · Schedule — pick days and hours, and it locks itself · Place — arrive somewhere you've saved, and it locks itself While a lock is running, the apps you picked won't open. Try one and you'll see the goal you wrote for yourself. ■ When you want to scroll, come here Focus breaks. You want to look at something. Open 1% and you'll find people fighting the same fight — studying, training, working. Only posts from people actually doing the work. Nights out and entertainment don't make it past the AI review. ■ The time you held out becomes a number · Total time locked · Day streak · Lock completion rate (how often you finish the locks you start) · Your rank and top % among everyone Keep going and the numbers grow. Quit early and that's on the record too. ■ 1% Elite (in-app purchase) · Schedule lock · Place lock · Exclusive app icons ■ About the subscription · Plans: monthly, yearly, or one-time purchase · Payment is charged to your Apple ID account at confirmation of purchase · Subscriptions renew automatically unless canceled at least 24 hours before the end of the period · Cancel anytime in Settings > Apple ID > Subscriptions Terms of Service: https://onepercent-legal.vercel.app/terms Privacy Policy: https://onepercent-legal.vercel.app/privacy
