The Zepp Tennis Swing Analyzer is a motion-sensor training system that helps you analyze and improve your tennis technique. It attaches easily to any tennis racket. The analyzer tracks forehands, backhands, serves and smashes, including the power generated with each stroke or over the course of a whole game. The Zepp also measures top-spins, slices and flat shots and records the amount of time you spent actively on the court. Finally, it allows you to analyse your swing in 3D from any angle.
Using the included racket mount (which can be used with more than one racket) or pro mount (which is taped to a single racket of your choice)—the Zepp captures over 1,000 data points per second, and wirelessly sends the information to your smartphone or tablet via Bluetooth. The Zepp sensor is also compatible with other Zepp sport apps: Zepp Baseball and Zepp Golf.
Ease of use
Use of information
The box includes the charger, the Zepp tennis sensor, flex mount and pro mount. The app is easy to download and install – sync-ing via Bluetooth was also no problem.
The Zepp is very noticable – and some players may find it a bit distracting – particularly as it will also slightly change the feel of the racquet
The pro mount is however more comfortable than the flex mount. The flex mount extends over the tip of the racquet, which means that if you hold your racquet very low, you will start to feel the flex mount. Which can be rectified by using more over-grip. The mounting system isn’t perfect, especially the Pro Mount, and has been known to fly off during play.
Getting the mounting sleeve onto the handle takes some patience, but it is not too difficult. The pro-mount requires you to apply the adhesive the first time – and leave the mount on for 24 hours so that it attaches securely.
You need to remember to calibrate the sensor before your hitting session. It is a fairly simple procedure of laying the racquet flat on the court with a particular part of the sensor positioned in the upper left corner. The sensor is then calibrated through the app. Skipping this step, however, causes the device to have a faulty reference point for strokes, and all the subsequent data to be skewed.
Zepp Tennis Application offers you two modes. The first mode is “Play Tracking Mode” which records your entire practice or match session. The data can be viewed through the online regime – or offline where the session the data is downloaded to the app for analysis. The second mode is “3D Serve Mode” which allows you to record and analyze your serve in 3D. It is best to use this mode in online regime for immediate feedback.
So, what information does the Zepp provide?
The data is very detailed. In the play tracking mode there’s a breakdown of number of shots hit by stroke: serve, forehand, backhand, and smash. Unlike some other sensors, it doesn’t calculate volleys. Each of those shots is then broken town in spin type: topspin, slice, and flat. There’s also a measurement that shows you how often you are hitting the ball in and around the sweet spot.
The 3D serving feature is basically a top-down, side-to-side rendering of a player’s serve. It relays racket speed, potential ball speed, a spin measurement, backswing time, and impact time. It is probably the sensor’s coolest feature and one that sets it apart from the Babolat and Sony tennis sensors. However, the 3d feature seems to be designed to be used solely during serving practice.
The interface takes a bit of getting used to, but the information is useful, and does help you to improve. As mentioned, it is very detailed. Whether you’re playing a match or just hitting around, practice should always be done with a plan and a purpose. Zepp helps you to visualise your game, analyze your swing data, and compare and track your progress over time.
In our opinion the Zepp is a great tool for amateurs or occasional players who are interested in better understanding their game. The sensor is well designed. The fact that it can be used with any racket is a plus – and saves on the further expense of purchasing a new racket. On the minus side, however, this means that the accuracy is probably below the Babolat and Sony tennis sensors – which require specific equipment in order to function properly. Overall, this is good product for players who wish to find out basic information about their game.
