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. For a quick reaction to bug reports and support questions please contact us by email. ### 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. ### 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 ### 3/5 — Notes editing *2025-11-21, version 2.1.3* Note editing is difficult. Slide to the left no longer stops nagging. ### 5/5 — Often several hours late - almost useless *2025-07-20* 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. ### 3/5 — Need true ongoing nagging *2025-07-11, version 2.1.3* 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. ### 5/5 — A calendar with a snooze function :-) *2025-06-11, version 2.1.3* Finally an IOS calendar app with the simple function of snooze! I find it hard to believe so few people use a snooze function on calendar reminders. For me it’s so important and useful so thanks for developing this calendar app. ### 4/5 — Favorite App but Glitch Since Update! *2025-05-06* This is the best calendar app there is. I have had it for many many years. The snooze function/nag function make this a must have app. I also love the different alarm sounds and the different calendar display style options. However with the latest iOS update, it now won’t let me update repeating events to a different day or time, not for a single event or future events. PLEASE fix this!!! Thank you! ### 3/5 — Cannot save changes in repeating events *2025-04-26* I am one of the people with this problem which you say is with the Apple update IOS 18.4.1. I appreciate your explanation in Troubleshooting. Do you have any idea about when this problem will be resolved? I deleted a recent repeating event & created a new one, but of course the same problem occurs with the new repeating event too. Prior to your own supposed upgrade to V3, I never had a single problem with CalAlarm. After upgrading & getting unexpectedly charged even though I was originally told I could get the upgrade for free before it came out, I have had to deal with several annoying issues, but I have always been able to work around them until now. Then they seemed to all be worked out. I still consider this to be the best calendar app & I can’t do without the nag feature, so I still do not want to change to anything else. However, with this latest glitch, I have to give it a lower star rating, down from 5 to 3. ### 5/5 — Nag option is A MUST HAVE!! *2025-04-26* I’ve been using this app for years and couldn’t be happier — I have no interest in switching to any other calendar. With a busy schedule and a tendency to forget things, I needed a calendar that would keep reminding me until I either stopped the alarm or snoozed it for later. Thanks to this app, I never miss an appointment! It’s an absolute must-have for me. I highly recommend CalAlarm! ### 5/5 — The Best Calendar App! *2025-04-25, version 2.1.1* 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! ### 3/5 — Pas de rappel *2025-03-18* Application jolie, mais n’affiche pas les rappels d’iOS Autre manque : pas d’activité en direct En l’état je n’achèterai pas ! À suivre les évolutions ### 2/5 — Pagando avete meno *2025-03-06, version 1.9.10* Con l’ultimo aggiornamento 28 febbraio non si legge più nulla nella visione mensile si vedono solo dei pallini colorati, così non serve a niente ## Most critical reviews (10 lowest-rated) ### 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. ### 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. ### 1/5 — Every So Often the App Just Stops Working *2025-11-19, version 2.1.3* Every so often this app just stops working. With the latest break—I can clearly see alerts in the “Overdue” tab, but there are not iOS notifications or audible alarms. This causes me to miss important meetings. ### 1/5 — Often several hours late *2025-07-15* 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. ### 1/5 — IS THIS A FREE APP? *2025-05-14, version 2.1.3* looks like app is free but requires a subscription or free trial only. which is it? ### 1/5 — Settings reset *2025-03-27, version 2.0.0* Downloaded the latest version of this app and many of my settings were reset. Very frustrating ### 1/5 — App Stopped Working correctly *2025-03-12, version 1.9.10* This app has been my lifeline for years until about a month ago it stopped working properly and your IT can’t figure out how to fix it. I can’t be the only one experiencing these problems on my iPhone. It no longer stops the alarms it’s the stop nag feature in Lock Screen so the app has basically become useless because I’m not going to keep my phone on all day in order to snooze or stop nag all my calendar reminders/appointments that I have on repeat each day for all my tasks. Please fix this! ### 1/5 — Set another alarm to open the app daily… *2025-01-27, version 1.9.6* Otherwise it doesn’t really work. Calalarm can’t update events in the background. Frustrating. ### 1/5 — Ruthless company *2024-11-27, version 1.9.3* Without warning, this company disabled the old version, a product I had paid for. They rendered the old app useless and forced users to upgrade to a new version that you must pay for. This is unconscionable and ruthless behavior. There is not another product like this, so you have no choice but to pay their ransom, to continue using the product. I do not like companies like this! This is shameful! ### 1/5 — Stopped working with phone and Apple Watch *2024-11-04, version 1.8.0* After a few weeks of the app working quite well it suddenly stopped and I can’t troubleshoot to a solution :( ## Most praised reviews (10 highest-rated) ### 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. ### 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. ### 5/5 — Nützlich *2025-10-17* 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. ### 5/5 — Calendar with options and benefits *2025-09-19, version 2.1.3* 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 ### 5/5 — The Best Calendar App! *2025-08-19* 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! **Developer response:** Just enable Month view Classic in Calalarm Settings in the Appearance section to see all days of the week. ### 5/5 — Mr RS Shergill *2025-08-17, version 2.1.3* Just brilliant ### 5/5 — STLL the BEST *2025-08-14, version 2.1.3* 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.
