Similar to what other users report, the app initially locks up and does not allow creation of an account. After multiple workarounds, I identified that you MUST ALLOW NOTIFICATIONS to create your account in Android; you can turn notifications off after you create the account. This is both sketchy and annoying. A free account gives you access to both "Crush It" and "The Ultimate Tennis Lesson." However, I cannot imagine paying $99 to subscribe to the additional content.

This app is horrible. It crashes. If it does't crash it won't let you sign in. Try to change the password it says no internet connection and no way to back out of the screens. I asked for a refund on a program I bought because I can't get to it through the app. I have yet to get reply back. Updating the review, I did get my refund which I appreciate

FYB does not respect their customers. I bought 5 weeks ago. The app crashed. The company did not reply to multiple support emails. I'm not the only one - read other reviews. Support responded after 3 weeks of silence to say try again; They had updated the app but never acknowledged this in the email. The app loads now, but I received no password. The app does not have a password reset option. And again support does not reply to my emails requesting the password be sent.
