A smart wristband to perfect your tennis swing

Smash, a new startup company, has unveiled a new smart wristband, which can monitor and record all your moves while you play tennis. The wristband uses motion sensors to track many aspects of your swing, shots and spins and favorite moves.

According to an article on Engadget, the Smash wristband is connected to your Android or iOS device and using an app, you can check your performance. You can know if your play needs more power or if your backhand is inconsistent.

Smash is a crowdfunding project, and the gadget will start shipping from February. It could carry a price tag of approximately AUD $129
