### 2/5 — All day feature

*2026-08-17*

Love this app but lately it has started to show double days for holidays and events in Canada. Remembrance Day, Christmas Day, New Years Day as well as others show 2 days. One extra day either before or after the holiday. Very annoying. Needs a good makeover by the IT people to stop this from happening. Otherwise, great app.

**Developer response:** Thank you for your feedback. Looks like you found a bug that is now fixed.

### 1/5 — Waste of money

*2026-07-27, version 2.2.1*

Cannot turn off the nagging of calendar events that were created in other calendars. Waste of money.

### 5/5 — Perfect for adhd, but..

*2026-07-14, version 2.2.1*

Can you please fix deletion of recurring events on first attempt? Sometimes I have to delete my daily meditations reminder three times for it to successfully delete for the day.

### 5/5 — The Nag is perfected!

*2026-05-23, version 2.2.1*

You’re busy just now, the reminder pops up, you can’t address it because your hands are full.  No worries, it’ll go away for a minute and come back to try you again until you cancel or snooze.  I love this app.  It’s run my life for years now !!! Thank you!!!

### 5/5 — 10 Jahre

*2026-04-29*

Ich nutze ihn jetzt seit über zehn Jahren und ich und meine Frau können nicht ohne ihn! Ich habe bis jetzt keinen vergleichbaren Kalender gefunden und ich habe bestimmt über 30 getestet und auch für viele gezahlt!

**Developer response:** Hi, Looks like you have a support question. Please contact us by email for support. Or visit the support page https://www.devart.nl/calalarm/support.html

### 5/5 — Life saving

*2026-04-27, version 2.2.1*

I use cal alarm for my medical appointments, even months away. Also for teaching astronomy classes and star parties. 
Easy to program. Relaible. Life saving. 
Often “Search” fails to find my destination. A minor problem.
I love and need Cal Alarm.

### 2/5 — Does not always do, what it should, define calendars every once in a while new

*2026-03-17*

The App says, it nags for calendar entries. Which is sometimes true,  but not always. I did not find our, which reminders are simply not set, and which reminders occur. 
The other problem, that (also randomly?) I have to uncheck all calendars where I do not want a reminder. E.g. I watch a calendar from a co worker, to see faster when we can work together, but Indefinitely do not want his calendar entries as an alarm. So randomly I have to uncheck his calendar in calalarm. I absolutely do not understand why this happens, but it is really annoying.
I donno why this happens, but I happens at least when you are forced to use MS365.

### 5/5 — Good working app

*2026-02-08, version 2.1.3*

Only $7 and family share. Works with Google and Apple calendar. You won’t miss an appointment again. You can customize how it alerts you.

### 4/5 — Perfect with some improvements

*2026-02-01, version 2.1.3*

If it had better text management (the ability to edit long, complex texts more easily and checklist-style features) and better graphics, it would be perfect

### 1/5 — Need a way to suppress Nag for some Google Calendar events …

*2025-12-03, version 2.1.3*

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.
