I have finally found the reminder app that does everything it claims it will do, consistently, and most importantly, intuitively, after trying many different ones. I have all of my daily, weekly, monthly, etc. repeating events imported and working.



It’s the best app I’ve found for keeping track of events and gives a variety of notification tones and snooze options, and it’s also the easiest to set up. A fantastic app to always have on your phone. I also love the feature being able to share the reminders.
