The application is Great because I get an audible notification that hopefully I will hear. The selection of sounds are limited and need to be improved. I am deaf in one ear and need long sounds and a better selection.
The instructions regarding making CalAlarm notifications work need improvement. I had to search the internet to figure out that I had to go to settings to turn off notifications in calendar to make Calalarm work right. Needs improvement, but works great for making certain I do not miss an appointment. Be careful however. If you accidentally turn off ringer by the switch it turns volume off on CalAlarm. I missed an appointment because switch was off and the app did not detect the switch being off and notifying me to turn on. Don’t know if possible to change software to help identify when switch is off, but would be nice.

Great app and worth having

Saves me

I would never remember to do anything without this app. I have used it for many years now and nothing out there compares. This is like having Outlook reminders in your phone. I set up "appointments" for everything I need to get done so it will remind me. I can snooze the reminder for how ever long or turn it off once I've completed the item. If it's something that doesn't have a specific deadline but that I just need to get done eventually, I'll set it up as a repeating reminder either daily, weekly, monthly etc so that if I can't get to it right when it beeps at me the first time, I can just turn that reminder off (rather than snoozing it) and I know that I'll be safe because it will remind me again tomorrow at the same time or next week etc. It's basically my to do list with reminders plus all my appointments for places I need to go all in one. Couldn't live without it.

Fantastic app

I likely downloaded the 1st edition of this app 6 years ago. I have also tried at least 2 other more expensive calendar apps, but I always come back to this one! Important features: nag alarm; easy to set snooze and appointment move functions so there is minimal interference with what you are doing; multiple customizable reminder, snooze, and move presets; interfaces extremely well with the native calendar so Siri can be used, can set for multiple recurring future events, etc, etc. It has many more features than the native calendar. One wish for the future: a customizable nag feature so you can set the nag interval (1 minute, 10 minutes, 30 minutes, etc) instead of the 2 preset options of either every one minute or every 1 hour. There is virtually never a day that goes by that I haven’t used this app!
