Like the Jawbone UP before it, the Jawbone UP24 ($150) is all about tracking your activity — like walking, pace, distance, and calories burned — and continues tracking your behavior after you're fast asleep. After synching the UP24 wirelessly with your iOS or Android device, you can check all your data and make new goals through the app. You can also program in other stats manually, like workouts, mood, and meals (the UP24 also syncs with third-party apps like MyFitnessPal). The small bracelet can also be programmed to vibrate at an optimal time during your sleep cycle to wake you up or even during the day to remind you to get up and move. The UP24 has a battery life of about seven days before needing to be recharged. For more on the Jawbone UP and UP24, read our extensive review here!
