The face exercises do not open well, and it would be good to choose other food alternatives in case you do not have the ingredients, and a progress statistic, the application is simple, but I think it does lack one or another update, how to add , if you are losing weight and an analysis of the process. I have been using it for 8 days and I like it but some things fail when doing the exercises. I used for 23 days but today doesn't work I feel disappointed 😓
