I am looking for an alarm clock app that does the following: 1) Can set alarm volume independently of phone's volume setting (i.e. I can have the phone's volume all the way up, but can set the alarm so that it will go off at half volume). 2) Works with the screen off/locked and the app running in background only (i.e. have the screen off, but don't have to have app open for the alarm to sound). 3) Simply brings up alert(s) on the lock screen with buttons to either stop the alarm or snooze it 4) Works even if Do Not Disturb is on I don't feel like those are terribly stringent requests, but I haven't found an app that meets those 4 requirements. The native app is pretty much ideal except it doesn't meet item #1 above (that I am aware of). Does anyone know of any alarm clock apps that would meet the above 4 "requirements"? Gracias, in advance.
