AVOID! Save your money!

The app isn’t really made for streaming on devices like Apple TV or an iPad which makes it really challenging to use and watch the videos while using the Castle Flexx.  The very first two videos for beginners is literally split in half and just start/stop abruptly.  It should just be one video.  I’ve spent more time trying to get logged in and play a video to the point where it’s not even worth the money!!  I paid for a year subscription and it’s awful.  I’m immediately turned off by the whole thing.  Absolutely terrible!! Stay far, far away from this company! Don’t buy any of their products. Their customer service is also the worst!!! After I gave CastleFit a 1 star review they offered me a 40% refund if I would change my review!

Horrible App

Not sure what they are thinking with the app. You might as well go to their website as this is not a Mobile app. For 1, I'm not looking to buy more products, I JUST bought a subscription to the classes and just want to use the videos that I subscribed to. I click on the castlefit login and classes login and I'm taken to my orders upon sign in and then when I move to go back I have to sign in again. Not user friendly and is very frustrating. If I could give negative stars, I would. Might cancel my subscription. They need 2 different apps if they want to push product and 1 dedicated to the videos!!

Needs a lot of work

I paid the subscription for the Flexxlab but it’s so clunky. What I see in the app does not look like the screen shots here. Typically I don’t even use the app to access the FlexxLab. I love the product but there is a lot of work that needs to happen to get the app user friendly. I typically get notifications there are updates but I’ve yet to see any. I won’t be renewing if not significantly improved.
