Doesn’t work
First, if you’re buying this you should know this is not set and forget alarm as you’d expect. You need to make the app active along with the music app for it to work. Most of it is due to apple’s restriction, but still a pain to use. Second, it’ll play using the speaker set in the control center. So if you’re using headphones, it’ll play the alarm with the headphones. The developer should have mentioned these caveats somewhere. Finally, the alarm doesn’t work. I made sure the app and music app were opened once before I went to sleep. The alarm didn’t work. I noticed there were a lot of notifications from the app when I woke up, but the alarm didn’t start.
