Rules of Tennis, the new app, seeks to show the obscure and interesting breaches you can make on the tennis court.

"As world governing body, the ITF is responsible for protecting the integrity of the game through the determination of the rules of tennis", the ITF said in launching the product.

"The new app will be an essential tool to communicate those rules, including the latest amendments, to the millions of people involved in tennis - from those at the top of the sport to recreational players across the world."

Also included will be rules for beach and wheelchair tennis.

The app can be downloaded for free.

It has been released as part of ITF's educational drive which saw their educational platform ITF Academy make their resources free.
