Tennis fans will be able to follow both the men's and the women's game on a single mobile app from Wednesday, marking a collaborations between the ATP and the WTA tours aimed at uniting the fragmented sport.

The new ATP WTA Live app will replace the ATP and WTA's existing apps and allow fans to keep up with official scores and results from both men's and women's matches.

That the sport still has work to do to reduce cracks in governance was evident as subscribers to the app will still not have access to scores from the Grand Slams — the four biggest tournaments in the game.
