Having a nice silent alarm that wakes you from a power nap is even nicer.

Sleep tracking with the UP3 is super simple – you don’t need to put the tracker into sleep mode – just go to bed and it will start tracking. Why is this important? Seeing your light, deep and REM sleep gives you an entire look at your sleep cycle – which is a great starting point for anyone trying to improve their sleep. It’s important to note that this tracker is one of the only sleep trackers that calculates your REM Sleep. When it comes to seeing how you slept, the chart breaks down your time spent awake, in REM (Rapid Eye Movement) sleep, light sleep and deep sleep. It’s ease of use and clear, easy to read graphics are perfect for the casual user and the power user alike. The UP App is one of the best apps associated with a fitness tracker on the market. This is actually a solid product – and one of the most advanced wearables when it comes to sleep tracking. Maybe their competition put out a lot of fake reviews on their Amazon page – but don’t believe half of them. You might even think you’re reading reviews for a different product. If you read the Jawbone UP3 reviews on Amazon, this fitness tracker will not impress you. While the sleep tracking capabilities are even more impressive than the UP24, the UP3 does have its ups and downs. The UP3 has more advanced features, including heart rate tracking, a new app and a different wristband design. This time we reviewed it’s upgraded version, the Jawbone UP3. Previously, we reviewed the Jawbone UP24.
