SmartMat (Pre-order for $297, ships Aug 2015)

With warmer weather often comes the motivation to get in shape by ramping up your fitness program. This deceivingly standardlooking yoga mat, in conjunction with the SmartMat app, uses high-tech sensors to help you get the most out of your yoga practice by providing real-time feedback on your alignment and balance. When you first set up the SmartMat, it will take you through a series of movements to calibrate your body shape, size, and personal limitations. It's like having your own personal yoga instructor in your home.
