I have ADHD. I can snooze a reminder, and completely forget about it within 30 seconds. So this app is a lifesaver for me as it keeps nagging me. The only thing I don’t like about the app, is that it seems to duplicate the reminders: it seems to keep the 15 or minute reminder that I set when I created the appointment but then also seems to create a duplicate 15 minute reminder on top of it, so I have to stop the nag twice every time it goes off. I’m sure that that is user error, but it’s not intuitive – at least not to me – how to stop it doing that. But the reason I’m only giving it four stars, is that every time they release a new version, I have to pay for it again. I really wish they would allow me to pay just once, and carry it to the new version. It kind of feels like I’m being nickeled and dimed. That said, if you have ADHD like me, I don’t know of a better app.
Developer Response
Hi, Thank you for your feedback. Could be you are getting a duplicate from the default iOS Calendar (with which Calalarm syncs). Please check the alerts from the iOS Calendar that you can disable as following:iOS Settings app > Calendar > Default Alert Times > Events. And yes you have to pay for V3. We have supported and updated Calalarm V2 for free since 2014 till early 2023. The new V3 app is built from scratch and is a new purchase.
Often several hours late - almost useless

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.
Cannot save changes in repeating events
Jaylu25
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.
Best calendar app but V3 continues to be buggy
UltimateBrianMorgan
I love Calalarm, but like other reviewers have indicated, this new V3 version is buggy. New updates seem to fix some problems while introducing more bugs. The current 1.5.2 version has two persistent bugs that I’ve contacted the developer about and have not received a response on. 1. When creating a new event, the calendar view often shows the next month on save but with the current month in the title. For instance, if I create an event for February 1 and save it, the monthly calendar will jump to all of the March dates, but the title at the top will still say February. This bug is intermittent. 2. When creating a new event and selecting “none” as the reminder, the reminder reverts back to either 10 minutes before the event or when creating an all day event, it adds two reminders for the day before and the day of the event. You have to save the event then go back in to remove the reminder and save again. It’s annoying. This bug is consistent. With that said, I still prefer this app to any of the other available iOS calendars. The alarm nag feature is especially indispensable. I just wish the current version wasn’t so buggy. V2 was flawless.
