The Jawbone Up24 is an upgraded, wireless version of the hugely popular Up fitness wristband. The Jawbone Up24 allows you to set daily fitness goals for yourself, and then tells you whether you've been meeting your goals or not. The contraptions also offers social networking tools that allow you to compare your progress and compete with others.
The Jawbone Up24's accompanying app displays your progress via colorful bar graphs. Meanwhile the app's main screen tells you how close you are to your daily goal, reminding you to keep working towards it. The home screen also includes a timeline of your recent activity.
The wristband works for about seven full days on a single charge, and charges from empty to full in about 80 minutes.
