    Through AlarmManager, you can only wake up your device when it is sleeping.

    To do that use
    setRepeating(int type, long triggerAtTime, long interval, PendingIntent operation)
    or set(…)

    with RTC_WAKEUP or ELAPSED_REALTIME_WAKEUP

    But it doesn’t work with a device at off.
    So you should consider having your alarms in a database, along with the last time your app was on, and count the alarms you missed since last time you were up.
