This app has features which its competitor, Tennis Trakker Pro, does not:
no-ad scoring, doubles play, 8 game pro-sets, and undo.
It does not record service winners (they are recorded as regular ground strokes) and the user interface is cluttered (background images more salient than icons, difficult to read text, cluttered icons, etc.) Tennis Trakker Pro DOES record service winners and the interface is cleaner (with the exception of that annoying "Is this correct?" dialog box you get with every point!)
Bottom line: Tennis Trakker Pro is missing too much to be useful (and its more expensive) so for the money, My Tennis Stats wins.
