This is still the only calendar I've used in the last ten years! I've tested at least 30 other calendars, but none of them come close! The most brilliant feature is the constant reminder for appointments, which repeats until you respond! You won't find that in any other app! What good is a calendar that doesn't relentlessly remind me of my appointments?

Infet woken up middle of the night as default Nag goes off indiscriminately for every Google calendar event. They should not Nag for Google calendar ebent with only email notifications. The support is neither open to new ideas nor helpful so far.

Ich habe bisher erst die Gratisversion ausprobiert. Mir gefällt besonders die Option, beliebige Erinnerungen für einen Termin einzustellen, also 5 Minuten vorher, 1 Stunde vorher, einen Tag vorher etc. Werde wahrscheinlich die Pay-Version auch kaufen.. Auch das ist angenehm, dass die Vollversion kein Abo ist.

Far better calendar app than the native calendar. Allows so many custom options for snoozing, resetting reminder for minutes hours or days later, so you don’t forget the task you need to get done

Just keeps getting better. The IOS calendar is trying to be as good with a similar look. But this app just keeps getting better. The snooze feature is unbelievably useful. It works! Simply the best Calendar app. I’ve tried them all. This is the best one. It works. And that is what it is suppose to do; works perfectly!

CalAlarm is still the BEST, provides a diversity of alerts, customizable alerts, and you can SEE the appointments—even better with a update. Make sure your iPhone is updated to prevent possible alert problems. If there’s a problem and you contact support, they will provide the solution. Thank you, Devart ❣️

The 6 day trial before I was forced to pay was not long enough to really determine if this program works properly. I frequently encounter the situation where alarms I should have received in the afternoon are not given to me until 9:30 to 10pm at night. This happened yesterday. And just now at 10pm I was given the alarm about a 7pm meeting. Thanks for helping me miss an important meeting!!!! I have been sitting here with my phone on, fully charged, audio on, frequently using Evernote or every couple of hours taking a break to play a game for a few minutes, or look something up on the web. None of the missed alarms had anything to do with appts recently added to my Google calendar. I depend on Google calendar, so maybe that is what this app is having difficulty with. Again today, there was stuff on the over due list that never triggered an alarm or nag. Now 8 hours past a Google calendar event I am finally receiving an alarm. The time zone is set properly on my phone, and Google calendar is properly synced.

This app is ideal for what I need, and I like it so far! But, I’m an educator and I don’t always hear or feel (vibration) the notifications even when I have them set a minute apart. Can you provide the option for a truly continuous nagging alarm? I need my phone and watch to continuously ring and vibrate UNTIL I acknowledge the alarm much like a wake-up alarm.
