Sometimes it works sometimes it does not work. Half the time when I click the top right alarm screen to view my different alarms nothing happens. To fix I have to close the app and then re-open it. When my alarm is set and I swipe between the different display screens it appears as though it overlays two screens on top of the other and again I have to close app and re-open. Most recently, If I set the alarm, set it to on, leave the app open, and lock my screen, the alarm doesn’t go off the next morning. Love the app concept and would use it all the time if the dev could just fix all the bugs. Not a single update in the last 6 months.
