Terms of use

What BallCheck does

BallCheck estimates how much bounce a ball has left from the sound of it bouncing. Results are estimates, not certified lab measurements, and depend on the court, the phone and how the ball is dropped.

Premium

BallCheck Premium is available as a yearly subscription with a free trial, a monthly subscription, or a one-time lifetime purchase. Payment is charged to your Apple account when you confirm the purchase, or when a free trial ends. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your App Store account settings. Any unused part of a free trial ends when you buy a subscription.

Fair use

Do not try to copy, reverse engineer or resell the app or its results as your own product.

No warranty

BallCheck is provided as it is. We are not responsible for decisions made using its results.
