Jawbone’s new fitness trackers aren’t the ones we’d recommend, but they’re getting a little better. The Up2, Up3, and Up4 can now automatically track your sleep with a free over-the-air update. The Up3 and Up4 also get passive heart rate tracking. [Jawbone]
Jawbone's excellent app will now sync with rival wearable devices from Fitbit, Pebble, Android Wear and yes, the iWatch, when it comes (via HealthKit). And oh, there's a firmware update for the Up24 that doubles its battery life from one week to two. What's not to like? [The Verge]
