What's New in Cannot Ignore

2.1.0

June 27, 2026

Now you can add sub alarms automatically to your reminder or calendar events. So you can set multiple alarms before an event, at an event, or even after an event! And you can adjust alarms so that you can keep them after they fire, for easy reuse later.

Best Alarm app

I never thought I would love an alarm app this much lol. I use it to help improve habits which I can do because unlike the native Apple alarm app which is limited to 24 hours for non-recurring alarms, Cannot Ignore lets me schedule alarms for any time in the future. The developer is responsive and even took on board a request that was extremely important to me. Thank you so much for making this surprisingly life changing (no exaggeration) app.

Finally

I’ve been looking for an app like this for years. I found one for android but then I switched to Apple phones so I was glad to find an app that does this. I could definitely use the help.

Excellent Customer Service & Experience

I had a few buggy issues with the app and reached out to support. I received an immediate response from Matt stating he was able to replicate the issue I was having and he had a bug fix released with in a few hours. The entire process was easy and not to mention how the pure existence of this app has made my life 100x easier. ADHD + endless work meetings = a recipe for disaster. I never miss anything now! Would 10/10 recommend.

STILL Poor Reminders Implentation

The app always stays active in the Dynamic Island.

Seems like another kludgy way to keep this app running.

I finally uninstalled.

Poor Reminders Implentation

App DOES NOT automatically sync with Reminders.

App shouldn’t require a Shortcut to sync in real time with Reminders.

Response from developer

Edit: Other users and our own testing verifies that syncing happens automatically with Reminders and Calendar. Could you send a video of what you’re seeing to hello@cephalopod.studio to pinpoint the issue so we can reproduce the bug? We should also note that no shortcut is required to sync in realtime. As long as the app is not force quit, it will add alerts to Calendar Events and Reminders automatically. Hello, we added more improvements to syncing. No requirement to play silent audio. Only that the user not force quit the app. Cannot Ignore syncs with Reminders and Calendar events in realtime. The app listens for any change in Calendars and Reminders, so that you don't have to even open Cannot Ignore to get your new alerts. (If a reminder does not have a date attached, it will not appear in Cannot Ignore, btw, if that’s an issue) If you would like some more back and forth troubleshooting, happy to help over at hell@cephalopod.studio!

FAQ

What does Cannot Ignore do?

Cannot Ignore is an alarm app designed to ensure you never miss important, one-time events. It features full-screen alarms that are impossible to dismiss accidentally, custom sound options, and smart integration with your calendar and reminders.

How does the full-screen alarm feature work?

When an alarm is triggered, Cannot Ignore displays a full-screen alert that takes over your device, regardless of whether you are on the lock screen, home screen, or using another app. This ensures the alarm is highly visible and cannot be easily ignored or dismissed.

Can I use my own sounds for alarms?

Yes, you can use custom audio files for your alarms. This allows you to upload any sound that will effectively grab your attention, such as a specific ringtone, a voice recording, or any other audio file, making your important alarms more impactful than generic system sounds.

How does the app integrate with my calendar and reminders?

Cannot Ignore can import upcoming events directly from your Calendar or Reminders. It automatically detects and includes details like video conference links, location URLs, event notes, and reminder links, so you can access them instantly when the alarm fires.

Is this app free to use?
