Not parent, but I mostly stick to FitXR and BeatSaber. I wanted to give supernatural a try, but the whole give up a credit card in the app when the headset already has one is too shady. I haven’t tried as many as I wanted to (like the bullet one) since I’m pretty happy with my routine.
I use it for warm up and cool down. I get my main cardio from FitXR, but if I’m just not feeling it beatsaber is easy to get into for some sweat at least.
