I've been using it for over a month now and I'm enjoy how easily it walks you through everything. I like that you can edit the workouts and keep track of your growth. It's also cool that it helps you calculate the nutritional value even of custom recipes you add in yoursef. The only issue I have is that when I try to see the warm-ups the app crashes. Please fix that asap. I think the app will be perfect after that. Thanks for a great app guys

I'm around two weeks into using the app, and my experience has been great. The usability and functionality of the app are next level. It's so easy to track calories by taking a photo of what I'm eating, and the workouts are fantastic. I'm already noticing differences in my physique, stability, and weight.

So far I have been loving the ease of use of this app, I find the subscription to be truly worth it. you get everything in one, calorie counter, workout routine specific to you and what you have available. And most importantly the knowledge of how to continue along in you journey. I'm just beginning, but from what I've seen and used I feel encouraged that this was a great choice.
