A new software update, announced on Tuesday means that the Up range of fitness trackers has caught up with the competition. <br />The Up2, Up3 and Up4 bands now automatically track owners' sleep thanks to the firmware update currently rolling out to the iOS and Android apps. <br />The upgrade also means that the Up3 and Up4 will be able to monitor heart rate - but only when asked. <br />As well as software, Jawbone is focusing on hardware. <br />It is launching a new, more subtly designed Up2 that will be easier and more comfortable for both men and women to wear. <br />What's more, the $100 device is now available in a choice of six new colours - violet, turquoise, black, grey, white and pink.
