Frequently asked questions

My alarm didn't fire — what happened?

CronPing schedules alarms as local iOS notifications, and iOS controls when they actually deliver. Common reasons a notification can be delayed or suppressed:

Notifications permission was disabled in iOS Settings → Notifications → CronPing.
A Focus mode (Do Not Disturb, Sleep, Work) is active and filtering CronPing.
Your device is in Low Power Mode, which may delay background work.
The device was off or out of battery at the scheduled time.

Which cron syntax does CronPing support?

CronPing supports the five-field cron format (minute, hour, day-of-month, month, day-of-week). Wildcards (*), lists (1,15,30), ranges (9-17), and step values (*/5) are all supported.

Can I add my own chime sounds?

Currently CronPing ships with a curated catalog of chimes. Custom user-provided sounds are not supported yet, but it's on the roadmap.

Does CronPing sync between devices?

No. CronPing is local-only by design — alarms are stored on the device where you created them. We don't operate any servers and there are no accounts.

How do I delete a lot of alarms at once?

On the alarm list, tap the selection icon, choose the alarms you want to remove, and use the bulk delete action.

Will the app drain my battery?

No. CronPing schedules notifications through iOS and does not run in the background between events.
