Tennis is a fun sport to watch. Federer, Nadal, and Djokovic make playing it look easy, but it is not. You need to be very fit and have the right technique to experience joy on the court. Smash happens to be a smart wearable device that could help you improve your game. This wristband can track your stats and techniques to offer your personalized recommendations.
Smash is lightweight and elegant. It analyzes your number of shots, racquet head speed, head momentum, amount of spin, wrist rotation, stroke trajectory, and technique. It looks good and has LED for status and notifications. Smash can go for up to 8 hours on a fully charge. Its companion app will be available on iOS and Android. The folks behind Smash are seeking funding for it on Kickstarter.
