About Lerf: Screen Time App Blocker

10 minutes on your phone turned into 2 hours. Again. Do Not Disturb stops notifications. Lerf turns your phone back into a tool that supports your goals. HOW IT WORKS Choose apps, set a schedule (optional) or tap start and distracting apps lock down. No streaks. No account. Nothing to check. Flexible Mode lets you end blocking early. Strict Mode keeps your apps blocked until the timer (or schedule) ends. FOR Focus: work or study without negotiating with your phone. Sleep: less scrolling before bed. Family time: set boundaries around distracting apps so family time means actually being together. PRICING Lerf is free to download. Full access is $12.99 a month or $39.99 a year after a 7-day free trial. Cancel anytime in Settings. WHY LERF Our smartphones are our greatest tools and our worst distractions. Lerf's mission is to turn smartphones back into tools, helping people take back control of their time, attention, and technology. PRIVACY Lerf uses Apple's Screen Time framework. Your app choices and usage stay on your phone. Lerf never sees them, and there's no account to create.
