Carl Petersen has invented an app that will improve the way cricket bowlers practice.

A University of Canterbury sport scientist has created an app that could change how some of New Zealand's best cricketers practise bowling.

Sports science lecturer Carl Petersen's newest app, XEQT-Pro, tracks where cricketers bowl and how accurately they meet their target.

It gives immediate feedback on their percentage executed and bowling figures, as well as more detailed performance information.

GEORGE HEARD/FAIRFAX NZ The app is available on the Apple and Google mobile stores, and doesn't require an internet connection to use.

Petersen said unlike many sports, cricket measured a lot of in-game performance aspects but not during practice.

"[XEQT-Pro] is pretty much aimed at trying to enhance performance in a training environment.

"If you look across other sports, they probably collect more data in training than they do in the game."

The app, which was about eight months in the making, was the latest in a career researching and studying cricket, from time at the University of Canterbury to working with Cricket Australia and as the lead strength and conditioning coach for Northamptonshire County Cricket Club in England.

Petersen has also played the game for more than 20 years and created another app, CricketPlaybook, in 2015.

"I've been around a lot of coaches and been exposed to what players are exposed to, in terms of what types of information [coaches] give and how it's communicated to the player.

"That type of experience has been crucial to just working out what works and different ways of doing things."

The app is already being used by performance analyst John Furlong with the New Zealand women's team in South Africa, as well as the Waikato Valley Cricket Association.

The Canterbury Cricket Association's assistant coach planned to use it when the second XI began training at the end of the month, "particularly with a white ball focus", Petersen said.

Continuing from fast local success, Petersen said his sights were set on India, the biggest market for the sport by far, and he had been working with two international PhD students from Chennai.

"I think that's a key market, looking at India in terms of how they love cricket, and also in terms of education – to attract Indian students.

"It was a definite ploy that we put [the price of the app] in rupees too."

Petersen said he hoped to be able to work with companies like those involved with in-game data gathering and performance measuring.

"I think partnering with an organisation like that, which is focussed on the game side, we could bring the training side to that kind of company.

"Our goal is to push that as far and wide as we can, change the way people are training, and make it more enjoyable, more engaging … especially for youth."
