I am on the verge of signing up to the Body Coach app. I need to lose at least 2-3 stone. It's £69.99. I'm super busy working full-time, single mom, and mom taxi 3 nights a week. I am hoping by actually paying for this I will use it as i never know where to start with free YouTube videos. Anyone recommend it or think it's a waste of money? Any other paid for apps better? Thanks!
