Lerf: Screen Time App Blocker

Start a session, put your phone down, exhale. Session-based blocking, built around relief instead of streaks and scores. Free for early users.

10 minutes on your phone turned into 2 hours. Again. Do Not Disturb stops notifications. Lerf stops the apps you open on autopilot. Start a session, choose what to block, put your phone down.

For sleep: block the scroll at bedtime. Your apps unlock in the morning. For focus: work or study without negotiating with your phone. For rest: put it down and actually relax, with ambient sounds while your apps stay quiet. For presence: dinners, walks, time with the people you care about.

Easy Mode lets you end a session early with a press and hold. Strict Mode keeps your apps blocked until the timer ends.

No dashboards. No streaks. No account. Nothing to check. Designed to be set down. Built for relief from apps designed to take your time.
