The serve is the only shot in tennis not influenced by your opponent and you have two tries. Therefore it is more than natural that you have certain location of serve you pick when you are under pressure or when you feel you need to hit your best serve. That is where GPStennis comes in. With this app you can track and analyze your opponent's serve and be well prepared. You can see how you win most of your points. What are your most successful patterns.
Statistics on the baseline game. Where you went for the wrong shot. Where your strengths and weaknesses are located. GPStennis does reveal these. You can see details on your location of serve, location of return - the details will be showcased in numbers and also in percentage
Tennis is “a game”. Those who know the rules of the game and are able to read the game will learn and improve much faster. Tennis is becoming more and more competitive and small details make a big difference in somebody’s game and their career.
Now tennis has changed and this stat may be different but can be even more specific with our app.
These become relevant for the mental part of the game and give them facts of key stats.
I have been coaching for 25 years and it does not matter how long and whom I coached during this period, every time I have to gain the trust from my players. Over the past 25 years I have always used facts to establish this trust because I could deliver the players with facts and figures that could help them become more objective in their shot selection and strategy.
Earning trust, does not only relate to coaches but also parents that are helping their children achieve their dreams. I have seen so many parents frustrated at the side of the court I wanted to give them something which would make their presence productive. Also GPStennis helps parents to learn the game faster and allow them to help their child. The parents would have facts and figures that they could share rather than just an opinion based on their observation.
I wanted to create an app that would allow the user to watch the match without having to fill in so many facts and figures that would be distracting. At the end of day we also want to enjoy ourselves while watching a match. GPStennis is made for the 21st century technology with 3 easy entries per point for tracking the entire match.
We are lucky if we know the service percentage during a match really lucky if we know the percentage of returns made. What about knowing if you made the return on breakpoint, even better where did you hit it and the outcome of the point. What about knowing where you or your opponent is serving on every 1st point of each game or on crucial points like mini break poinst like 15-30 or 30-30 as well as every break point.
Because all points start with a serve and return we can locate patterns of play. This can be done in your own game but especially in your opponent’s game. The tracking allows you to pint point the location of every serve and on key moments during a match or in a specific game. The analysis is the essence of this tool as you can navigate through every crucial point where was served and the return response was.
You will be able to get all this information after entering each service location and each return location followed by the outcome of the point.
There is also the function for entering a voice or written notes while tracking the match. This allows for specific feedback with the crucial outcome of serve and return information.
