Rest timer with music – Gravitus - Workout Tracker Review

My only complaint with the current version is that the rest timer doesn’t work when I’m using music. Instead of a notification could you make it just beep? If something else is playing then lower the volume of the music or whatever and beep overtop of it. I know I have other apps that are able to do this, it would make the rest timer actually usable for me.
