Cyclic Alarms: Shift Schedule Alarm Tool

Cyclic Alarms is a tools app by Pramod Beema that lets you set alarms that repeat every N days from a chosen start date, instead of only weekly. It is designed for people whose schedules follow rotating shifts, work cycles, or any repeating pattern that does not fit the standard Monday-to-Friday week. The app is free, contains no ads, and does not require any sign-in or tracking.

Most alarm apps assume a weekly routine. If your work pattern repeats every 3 days or every 5 days, you normally have to set each alarm manually every time. Cyclic Alarms solves this by letting you pick a start date and an interval, and the alarm will fire on that cycle indefinitely. It also supports traditional weekly alarms for those who prefer that, as well as multiple countdown timers and a stopwatch with lap recording.

The app is lightweight at 1.8 MB and works on devices running Android 7.0 or later. It includes eight built-in synth alarm sounds generated in code, or you can use any audio file from your device. The interface offers a true AMOLED black dark mode, a bright theme, and a system option with a brightness slider. It can ring even in Silent or Do Not Disturb mode, and it keeps a history log of past alarms. This makes it a practical tool for shift workers, students with rotating class schedules, or anyone who needs a repeating reminder that does not align with a weekly calendar.

Cyclic Alarms is for anyone with a repeating schedule that does not fit a weekly pattern, such as shift workers, rotating roster employees, people on medication cycles, or those with recurring tasks every few days. It is also useful for anyone who wants a simple, ad-free alarm with multiple timers and a stopwatch.

When setting a cyclic alarm, double-check the start date and interval to ensure it matches your schedule. For a repeating cycle that falls on different days of the week, the app calculates correctly from the start date. You can adjust the snooze duration per alarm, and if you want a unique sound, pick any audio file from your device. To avoid missing alarms, test the alarm once after setting it to confirm the sound and volume are as expected.

Cyclic Alarms fills a niche that most alarm apps ignore: alarms that repeat every N days. It is a lightweight, ad-free tool with practical extras like multiple timers and a stopwatch, making it a solid choice for shift workers and anyone with a non-weekly routine. If your schedule does not fit a standard week, this app is worth trying.
