Is there an app that can control the volume of notifications for separate apps like SMS and Gmail? I searched around and found a number of old threads that says it's not possible. There was an app called WhoIsIt that did what I was looking for but it seems to have been discontinued.
Otherwise I guess I'll have to make a custom ringtone that's louder than normal and use different ringtones for SMS and Gmail.
I'm on Android 2.3 btw.
