Jawbone UP4

Strangely enough, Jawbone has yet to even release the predecessor to the UP4, but the company has already announced their next big wearable. The UP4 is a sleek and highly functional wrist wearable that can track your heart rate, sleep patterns and physical activity. Not impressed yet? How about the fact that the UP4 can also act as a mobile wallet, allowing you to leave your thick piece of hunky leather at home?

Unfortunately, the mobile wallet feature will only be available to American Express cardholders due to American Express partnering with Jawbone. Of course, those that don’t already have an AmEX card will be invited to apply when purchasing their UP4. The Jawbone UP4 will ship this summer and will retail for $200, just $20 more than the UP3, which will begin shipping later this month. So if you’re looking for a fitness tracker that’s also an American Express-only mobile wallet, the UP4 is for you. [Purchase]
