Because our functions in the app are all personalized users are not recommended to share the app. More specifically, if you have two athletes that want to use the Athlete Development app for personalized training and/or nutrition, they should each have their own account. That would require them to each to download the app on a unique device and sign up on their own. But remember, the app is free. So everyone can download their own version and use it to their personal benefit at no cost.
