Cyclic Alarms

Alarm app for shift schedules — repeats every N days, not just weekly
A simple, 100% ad-free alarm app built for people who work shift schedules, rotating rosters, or any repeating cycle that does not fit a standard Mon-Fri pattern.

Most alarm apps only support weekly repeats. If your work schedule repeats every 3 days, every 5 days, or any other interval, you are stuck setting alarms manually each time. Cyclic Alarms solves exactly that. Pick a start date and an interval, and the alarm fires on that cycle forever — no manual resetting needed. It also supports regular weekly alarms.

Features:
• Cyclic alarms — repeat every N days from a start date
• Weekly alarms — pick any combination of weekdays
• Multiple Timers — run up to 5 independent countdown timers simultaneously
• Stopwatch — elapsed time tracker with lap recording
• Background Timer and Stopwatch via Foreground Service
• 8 built-in synth alarm sounds (generated in code, no audio files bundled)
• Custom audio — use any audio file from your device
• Rings in Silent and DND mode
• Pure dark mode (true AMOLED black)
• Dark / Light / System themes with brightness slider
• Per-alarm snooze duration with live on-screen +/- adjustments
• Strict lock screen security — only shows over keyguard while ringing
• Alarm history log
• Zero ads. Zero tracking. Zero sign-in.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
