Alarm with rising volume?

I want an alarm clock with an alarm volume that:

a) increases gradually,

b) is not the same as the ringer volume

i want all the othe alarm features of the Clock app, such as the ability to have multiple alarms that repeat on different days.

Bedtime does not seem to be what I want.

I tried looking for a 3rd party app but have not found one. Progressive Alarm seems close, but you have to remember to turn it on it every night before going to bed - that’s no good for me.

This is the kind of thing that frustrates me about iOS. A fairly simple feature (available on Android phones) that seems to be simply not possible.

suggestions?
