About

DoneLock is a persistent reminder app for recurring tasks, medication reminders, and daily routines. Keep due tasks in view, snooze within a set deadline, and hold to mark them done. If you often dismiss an alert and forget the task, DoneLock gives you a clear place to return to. Use it for an ADHD-friendly task check-in, a vitamin reminder, reading, or planning tomorrow. HOW IT WORKS 1. Name your reminder and choose a time. Repeat it every day or on weekdays. 2. Open a due reminder to act on it. Hold to confirm completion, or snooze while there is still time before your deadline. 3. Review Done, Done Late, and Missed records in History. A missed reminder stays available so you can record a late completion. START WITH TWO FREE REMINDERS Keep up to two active reminders, with one time per reminder and daily or weekday repeats. Hold-to-confirm, snooze, missed reminders, history, and completion stats are included. FIT MORE INTO YOUR DAY WITH PRO A DoneLock Pro subscription unlocks: - Unlimited active reminders - Up to eight times per reminder each day - Your choice of weekdays, such as Monday, Wednesday, and Friday Use multiple times for a recurring check-in or choose the days a routine actually fits. Pro is optional; the core reminder and history features remain available within the free limit. KEEP YOUR ROUTINES EASY TO FIND All Reminders lets you edit an active schedule even after today's task is done. Choose a missed deadline and optional follow-up alerts in reminder settings. Follow-ups are limited; opening DoneLock refreshes upcoming follow-ups. Reminders and history are stored on your device. Alerts require notification permission and follow your iPhone notification settings. DoneLock keeps task status visible in the app; it does not prevent system notifications from being dismissed.
