In addition to the usual stats (shot type, spin, power, etc.), the Pop can also track other metrics, like your overall playtime and your longest rally. As with its Play series rackets, Babolat touts the Pop's social skills, which allow you to share your favorite matches with friends and compare yourself to other users and -- if you're up for it -- actual pros. If you want to see how you stack up against Babolat-sponsored players like Rafael Nadal or Caroline Wozniacki, here's your chance. You can also design and issue challenges -- if, say, you're rather proud of a particularly long rally and you're curious if your friends can top it.

The $179 "Babolat and PIQ" wearable

Babolat and its development partner PIQ (which specializes in sports sensors) expect the Pop to ship in the US this fall for $90. In addition to the tennis-specific Pop, PIQ also announced the $179 "Babolat and PIQ" -- a more advanced model that uses the latter company's multisport sensor. Like the Pop, the "Babolat and PIQ" comes in the form of a wristband-mounted sensor that records your stats in real time. PIQ says its multisport offering tracks data using 13 different axes and includes NFC, Bluetooth Low Energy and a built-in display. Despite the differences in price and features, PIQ says both models will share the same user community.
