Take your attention back. You open an app without thinking. Five minutes quietly become fifty. Relock puts a pause between the reflex and the scroll — just long enough to remember what you actually wanted to do. CHOOSE WHAT NEEDS PROTECTING Select apps and categories through Apple Screen Time controls. You decide what matters, not a preset list. BUILD A RULE AROUND YOUR DAY Schedules, durations, daily limits, rule modes. Shape the boundary that fits your morning, your work session, your wind down — from a light block to strict mode when you really mean it. A PAUSE WITH A PURPOSE When a protected app is restricted, Relock creates a clear interruption with the context of your rule. Not another notification. A moment to choose. CHANGE IT WHEN LIFE CHANGES Edit, suspend, resume, or reset your rules. No two days are the same, and your boundaries should not be either. PROGRESS WITHOUT PRESSURE Interventions, estimated time saved, streaks. Information, not judgment. CALM BY DESIGN A focused interface and restrained feedback. An app that helps you look at your screen less should not demand more of your attention. YOUR PRIVACY Relock does not read your messages, your photos, or the contents of restricted apps. Apple provides opaque selection tokens that stay local on your device. JSON export and account deletion are available anytime in Settings. Start with the app that steals five minutes. Build the pause that gives them back. Relock is built around Apple Screen Time controls, for iPhone.
