Read full description

DelayLock turns plans into focused action. Choose a focus session, block distracting apps and websites, and pick a reminder that says what this session is for. FOCUS TIMER Choose 15–120 minutes in five-minute steps. With Screen Time permission, block all app and website categories or use one of your own blocking groups. Follow the countdown on your Lock Screen and Dynamic Island. FOCUS AND BREAK CYCLES Optionally alternate focus sessions with short breaks and take a long break after a few rounds. Blocking pauses during breaks and resumes with the next round. WHAT THIS SESSION IS FOR Pick an incomplete item from Apple Reminders, or add a new one, and keep it on screen while you focus. When the session ends, you decide whether to mark it complete. SCHEDULED BLOCKING Set working hours by weekday, such as 9 to 6 with an hour off for lunch. The selected group is blocked automatically and released during breaks. RECORD YOUR PROGRESS Review daily focus time, completed sessions, and a focus calendar. After a completed session, record what you accomplished. EARLY EXIT Use a rewarded video or a shake challenge to end a session early. Time already spent focusing is recorded, while the session does not count as a natural completion. Permissions and language: App blocking requires Screen Time authorization. Reminders access is requested separately and is used only when you pick a reminder or mark one complete. Focus records stay on your device and are not uploaded to a custom server; system accounts may sync reminders through iCloud. The app interface is currently available in Simplified Chinese.
