Activity Trackers come in many variants with different features, styles and functions, making it hard to narrow down which might be the best option for you. There's also the cost to factor in and many activity trackers can end up being upward of $150 or more. The Jawbone UP3 for example normally costs $179.99, but right now you can pick it up on sale for just $98.44 in the black twist style which is a rather good deal on a tracker with these kinds of functions.
Jawbone also has other colors available at $99.99 just in case black is not your first choice. The Jawbone UP3 has plenty of useful features like tracking your sleep habits so you can analyze the data and attempt to get a better night's rest, and of course it will track your steps, your calories burned, your pace, your intensity of workout and more. It also has a built-in smart coach to guide you toward your fitness goals and it can keep track of your resting and passive heart rate throughout the day. You can also use it as a smart alarm and if you're sitting idle for too long it will alert you to get up and do something active. This deal is Amazon's Gold Box deal of the day, so the cost won't stay this low for long.
