No more useful than calling your vet, they can't do much of anything. Not worth $25/mo. I had to cancel through my Google account because the subscription page always says my session is expired even when I log out and back in, but all the other account changes work fine. You can cancel through your Google Play subscription list in the Play Store settings if youre having issues. The only upside here is you get a 7 day trial so I didnt waste money.
