Smash—World’s First Responsive Coaching Wearable for Tennis

With Wearables all set for explosive growth, there are many new devices coming up in different sectors. We have covered quite a lot of wearables in the health and fitness area and now we have a new wearable device which is aimed at the sports segment. Smash is a new wearable device for the Tennis players and it is a lightweight wristband combined with an app that provides easy access to technique analysis and personalised recommendations.

So if you play Tennis, this should be an exciting way to measure your game play stats. Smash gives you insights and tips to keep you on the right track whenever you are playing the game.


When you use this device while playing, it measures all the data and converts them using the algorithm and sends it back to your phone using Bluetooth and you can analyse the details on your smartphone.
