User reviews

Terrible, worthless

The Castle Fit membership is worthless. Unable to sign in for weeks on the app to access classes. Castle Flexx is unable to resolve the issue despite promises to do so. Don’t waste your money.

Product is great, App is hot garbage

App is mostly marketing trying to sell me the product. I already bought it, just stop!!! I purchased a membership for the videos, but literally can’t get one video from the app. Just puts me in a perpetual loop for login, and then shows ,y receipt showing I did indeed pay, but can’t access any videos!!! Other reviews show this has been a problem for years. They need to fix and/or refund any membership costs.

Product is great, app and videos are terrible.

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!
