I miss many calendar reminders because they're just too subtle. I might put my phone down and walk out of the room for 5 minutes, missing the reminder, then come back and not touch my phone again for an hour; completely missing an important appointment.

If reminders worked like alarms, they would make their notification sound continuously (up to a point, like alarms: ~10 minutes), and take over the whole screen, until silenced. That would be preferable to me. Is there an app that can do this?


If you want to stick with your Google Calendar as backend and frontend, you might wish to check Calendar Event Reminder. You can tell that app which calendars to look at, and to annoy you until you're going crazy. I almost guarantee you cannot miss such a reminder! I've used the app for quite some time, before...

I switched to a different calendar frontend: Business Calendar. Very configurable again, also concerning reminders: vibrates and makes "subtle noises" (I've told him so) until I lose my nerves and switch it off :)

There are probably a lot of similar approaches. But I know of no way to even come near to one of them without any 3rd party tool being involved.

    Warning: Calendar Event Reminder was using a pay-for-ratings service. It's actual ratings are far far lower. Note the precipitous drop earlier this year. I have not looked at this product myself, just warning y'all to be cautious. – Myrddin Emrys Sep 21 '16 at 16:47

You can copy the mp3 file that you'd like (for example a 5-minute song) to the Notifications folder in your Android (at the same level that the Download folder). This can be done as well for ringtones (Ringtones folder) and alarms (Alarms folder). Now, go to calendar Settings, General and change the tone to your mp3 file.

  • Thanks. Can also add vibrations in Settings > General. Works for me – DrGeneral Sep 24 '17 at 4:46

I found a free app, Calendar Event Reminder, that achieves the requirement at https://play.google.com/store/apps/details?id=sk.mildev84.reminder


What I do is to set an additional alarm in my standard android "Clock" app. Alarms have the option to give them "memo text", e.g. "Reminder for meeting boss in 10 min". So the alarm will act as your intruding and persistent reminder. The alarm has also the option "Auto-start app", where you can select after switching off the alarm the calendar to be opened, showing you that you have an appointment in x min.
