I started this today, but it seems like an amazing app, kinda reminds me of Duolingo, great layout, easy to use and understand I do wish it had a little more games for young teens, I am one myself and do enjoy the concept of rewards and games to get to my goals, but if it had maybe more bright colors and silly things around, would be nice, but overall great app, i did recommend to my friends <33

Been using this App for sometime, however the performance has definitely declined. Not sure why does it keep loading while adding food???
