User Reviews

CalAlarm is praised for its powerful, highly customizable nag/reminder system and cross-calendar support, plus a one-time price and a clean UI. However, multiple reviews cite reliability problems (missed or delayed alarms, background syncing issues), post-update bugs, and frustrating monetization (ads, forced upgrades). Overall, long-time users rely on it to stay on task, but stability and pricing remain notable concerns.

Pros

Powerful nag/reminder system with customizable snooze, repeats, and multiple alert sounds.
Works with Google and Apple calendars, keeping you from missing appointments across platforms.
One-time upfront price with no ongoing subscription.
Clean, intuitive UI with flexible display options and a solid multi-alarm feature.
Reliably helps users stay on task and reduce stress by ensuring reminders are seen.

Cons

Alarms and notifications can fail to trigger or be delayed, leading to missed meetings.
Bugs and instability after updates, especially with the V3 version, including snooze/dismiss and background syncing problems.
Ads clutter the calendar view, reducing readability.
Pricing and upgrades can be opaque or force-paying for newer versions.
UX issues like difficult note editing and inconsistent nag behavior (e.g., lock-screen nag can't be stopped).

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!!!

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.
