Big Fan of the App

This is an awesome app. Love that you can track, have the guided workouts and coaching throughout the way.
If you are looking for something that will guide you on the journey and you can focus only on the next step then this is a great option.

Ridiculously high-quality!

Both the food logging and exercise guidance halves of this app are exemplary. Not only that, but there are regular updates with new features. Worth every penny! I am so glad I got this. (been using it for 90 days.)

Best fitness App!

I've used many fitness apps but this one surpasses all of them. Ever since I started following BWS in May 2026, I've dropped 11kgs I've gone from 27% body fat to 18%.

Im going to recommend this to friends and family.

Great app

The app really helps keep things organized in one place. I appreciate the videos for the exercises showing form, and I love the built-in timer for rest; it keeps the workout flowing nicely and feels efficient
