Can set alerts when YOU want them.

This is a very useful app. If you want to set an alert reminder the night before an appointment or you need three hours to prepare for something (not 2) or you know you will need more than a 1 week reminder to shop and mail a gift to get it there, this is for you.

There was an issue with numbers and time intervals not showing but the developer has fixed that.

You can modify any Calendar event notification by tapping on the event in this app or you can create a new event and time in this app, then tap the + to choose and set the custom alert interval. If you need to add Repeat, Invitees, etc., tap Edit Event from the Set Alert page to get the full iOS/iPadOS event edit page. It all goes to the iOS/iPadOS Calendar. Very helpful app!

Developer Response ,

The newer versions of Custom Alerts support adding and editing events within the app, so you no longer have to go through the cumbersome process of switching between Custom Alerts and Apple’s calendar app. Look for the + button at the top right of the main screen.

Can’t see to use it

When I go into the event to update the alert I cannot see anything other than set alert. On part of the screen I can “feel” a dial spinning which I assume is changing the time. But I can’t see anything. App is basically useless

Developer Response ,

Apologies for this frustrating experience. You uncovered an incompatibility when devices are in dark mode that had slipped through testing. Updating to version v2.10 will correct the issue.
