Smash tennis coach Review

Shop For This Product

We’ve seen a lot of general fitness wrist bands hit the market in the past year or so, with calorie counting, pedometer tracking, GPS and other factors built in. But what about something a bit more specific? That’s what Smash is hoping to do, with a wrist band that acts as your personal tennis coach.


Tracking the way your body moves and swings at the ball, the little wrist band is able to track some quite in-depth aspects of your game. Looking at the way you hit the ball and your own personal goals, the app, which wirelessly (via bluetooth LTE) connects to the bracelet, can give you stats on how consistent your topspin is, offering tips on how to control your racket’s acceleration or to further extend your follow through.

After you finish a game, you can look back at your Smash stats and see how often you used certain strokes, how often you were able to achieve a good serve and more. Based on these statistics, the in-built coach will then offer pointers on how to improve.

Over time, these stats can give you a breakdown of how you’re progressing, as well as setting personal goals for the future. There’s also achievements and challenges to take part in, such as hitting a new top speed for your serves, or getting the best score for every app user in your local area. You can even be ranked with other users around the world if you want.

The creators – who just started their Kickstarter for the device – are quite proud of how it looks too, saying that the Smash blends a mixture of function and fashion, to create a device that’s useful too have around and doesn’t look ridiculous on your wrist.


The Smash wristband features 6-8 hours of battery life and comes in three different sizes, small medium and large. It’s flexible and breathable and features an LED notification for indicators of certain goals being hit and that it’s turned on.


As it stands, you can get an early bird special of the Smash for just $130 Australian (£71) though that cost will go up to $200 when the product is finally launched.


Besides the fact that the Smash won’t be available until February next year (hardly the best time for tennis), it might end up being a little expensive for what it is. Presumably if you’re going to buy this type of gadget to improve your tennis skills, you won’t mind stomaching the cost, but I’d like to see apps for different sports made for the same wrist band. It seems swimming, football or any other number of sports could benefit from a device like this, making it much more affordable.

Bottom line

I’m quietly curious to see how this one turns out, as it has a lot of potential, but I’d want to see a omni-sports version rather than just one being catered too. Pretty much every sport could benefit from something like this, not just tennis. That should be exploited to add value to the product.
