The whole timer/alarm app experience in iOS is also the worst of all mobile OS's I've ever used. The best one was in Jolla SailfishOS. In 2014. It was so easy to add/remove/enable/disable multiple timers and alarms. And when they triggered, you could snooze or dismiss it with a simple gesture.

In iOS, you can't even have more than one active timer at a time. Like wtf??? Also, when the timer or alarm clock triggers, you are presented with view containing two buttons (yellow and purple). One of them snoozes, one of them dismisses. Which one is which, you ask? You see, to keep things simple and consistent, the button actions (and labels) switch places depending on whether the view was triggered by an alarm or a timer. Oh! and the label text color is white, which makes it reeeeeeally difficult to tell which of the fucking buttons is which, especially in a rush or in the morning when your eyes are foggy.

I would have replaced this shitty ass app in a heartbeat, except Apples strict controls kneecap all third party apps by preventing them from running in the background...
