About Lerf

My friends and I had this low-grade anxiety we couldn't pinpoint. It was the loop. Open an app, scroll, feel worse, repeat. At dinner, at work, in bed. I built Lerf to break it. Start a session, pick what to block, put your phone down. That's it. Easy Mode lets you end early with a press and hold. Strict Mode keeps apps blocked until the timer ends. No account. No streaks. No dashboards. Nothing to check. Free on iOS. Designed to be set down.
