Read full description

Pact helps you build a healthier relationship with your phone by adding intentional friction to distracting apps. HOW IT WORKS Select apps you want to limit. Start a focus session or set usage limits. When you try to open blocked apps, complete a quick puzzle first. The small pause helps you decide: do I really need this right now? FOCUS SESSIONS Block distracting apps for 15 minutes to 4 hours. Perfect for deep work, studying, or quality time with family. USAGE LIMITS Automatically shield apps after 15 minutes of daily use. Complete a puzzle to unlock 15 more minutes. Difficulty increases with each unlock and resets at midnight. EARN KEYS Earn 1 key for every 15 minutes of focus time. Use keys to skip puzzles when you really need access. Build a balance of keys as a reward for staying focused. WHY PACT? Unlike harsh blockers that frustrate you, Pact creates a mindful pause. The puzzle isn't punishment—it's a moment to reflect on your intention. Most people find that by the time they finish the puzzle, they no longer want to open the app. PRIVACY FIRST Your app choices are protected by Apple's Screen Time framework and never leave your device—we can't see which apps you block or what you do on your phone. No account required. We collect anonymous usage statistics to improve the app, and nothing is ever sold or shared. PACT PRO Block unlimited apps for free. Upgrade to unlock all session durations, detailed statistics, and support indie development. Download Pact and reclaim your attention.
