Just wanted to update: all the early bugs are gone and the user interface is cleaner and the stats are more thorough. Good just got better!
Follow up to my earlier review: I am very impressed with how quickly the developers respond to feedback and bugs. I have made suggestions that were already being worked on and have found the app only getting better with time. Warning-you have to practice with it. Once you do, youll find a good rhythm and keep better stats.
On to my original review: TennisStats is better that Tennis Trakker because it has an undo button for mistakes, it supports both singles and doubles, and it features various scoring formats (8 game pro-sets, third set tiebreaker, and even five set matches. I like that the scoreboard stays at the top throughout the point tracking. You can add a point without tracking if you accidently miss one. Id like an overall unforced/forced error summary in addition to the specific shot summary and the buttons could be a little crisper (no need for the cute tennis player background). Better value than Tennis Trakker, too.
