Amazing inspiring.


First of all let me state that Katy Hearn and Haydn Schneider are absolutely amazing incredible trainers that truly care about the client experience. She clearly states that you have to purchase a challenge in order for the app to be available for for use, never pretended like it was anything different. I am so grateful to have these two as my trainers and I’m so excited to see where this journey takes me the app is absolutely incredible i’m so grateful to have these two as my trainers and I’m so excited to see where this journey takes me the app is absolutely incredible and so easy to navigate. You’re putting in so much time and effort to continually update the app and make it a better experience for their clients
** please do not listen to the trolls that one star this app because they clearly have a personal issue. This is a client experience it’s not a YouTube’s videos... yes you have to pay money to have accountability from your trainer and have them update your macros on the weekly basis**

Amazing People!

Katy and Haydn go out of their way to make everything perfect for their customers. The app had some glitches at first, like any app would, and Katy and Haydn handled it with such patience. I truly applaud them for being so down to earth and professional. They had many many people asking the same questions or not paying attention to what was told and they answered everything with a professional attitude. This app is made for client experience and is not very useful if you are not part of her challenges. She made this very clear from the get go, yet some people still don’t understand that. This app is beautifully crafted and easy to use. Katy and Haydn take everything we suggest and try to work toward making it even better than it already is.

I am proud to be a client of Katy and Haydn!



This app is pretty great. Yes, there was some minor glitches but they responded back immediately and told us that they were going to try and fix it immediately with a few updates ahead. Definitely shows that they care about the quality of the app. I’m really satisfied with the app and I’m really excited to start!
-Those who did not buy the challenge are a bit upset that there’s not more for them, but look at the other programs offered on Instagram by popular fit people. They’re about the same price or even more, but Katy really spent her time providing something more for her girls which I really appreciate. She wanted to make it special for us, which she did!
