I went a bit deeper, found some more ios apps but did find a couple ok sound playback apps for Android and added them to the list.
Sound Trigger https://play.google.com/store/apps/details?id=net.soundtrigger&hl=en
Stage Manager (in the SM section of my list) does do some limited playback. https://play.google.com/store/apps/details?id=com.montysmagic.StageManager&hl=en
