Ripple Alarm: Repeat Reminder

Your phone's alarm handles daily or weekly repeats. Ripplealarm lets you create interval alarms that repeat every 1 to 99 hours, days, weeks, or months.

Need a medication reminder every 3 days? A plant-watering alarm every 11 days? An HVAC filter reminder every 3 months? Set it once and Ripplealarm automatically schedules every future occurrence.

— THE FLEXIBLE INTERVAL ALARM ANDROID HAS BEEN MISSING —

Ripplealarm is a custom repeat alarm app for schedules that do not fit fixed weekdays or calendar dates.

Choose any number from 1 to 99, then select hours, days, weeks, or months. Create alarms every 2 hours, 7 days, 6 weeks, 3 months, or any other supported interval.

If you have searched for "alarm every 3 days Android," "reminder every few hours," or "medication reminder every few days," Ripplealarm gives you the flexible schedule your built-in alarm does not.

— HOW IT WORKS —

1. Set the alarm time
2. Choose an interval from 1 to 99
3. Select hours, days, weeks, or months
4. Add a label and category
5. Ripplealarm fires and automatically schedules the next occurrence

Get a complete alarm experience with a full-screen alert on the lock screen, alarm sound, snooze, dismiss, and the option to skip the next occurrence.

— BUILT FOR SHIFT WORKERS AND ROTATING ROSTERS —

Work a 4-on-4-off schedule, every third day, or another rotating roster? Weekday-based alarms cannot reliably follow schedules that move across the calendar.

Ripplealarm counts the interval instead. Set a wake-up alarm every 2, 3, 4, or up to 99 days, and let it continue following your rotation.

Ideal for firefighters, nurses, security teams, mining crews, ferry crews, and anyone working a repeating schedule that does not match fixed weekdays.
