Customers like the sleep tracking of the wearable computer. For example, they mention they really like the accuracy of the heart rate sensors during workouts, and that it monitors their daily activity level.

"...The down side is the battery life is pretty poor.Once or twice the screen was stuck blank and had to reboot the watch...." Read more

Delivers what I wanted most: Data!

Delivers what I wanted most: Data!
I shopped around quite a bit for a replacement for my Amazon Halo which was my first fitness tracker. A lot of trackers have extra features that have nothing to do with fitness so I don’t need them. I was looking for accurate data and this seems to do really well. The battery only lasts about 3 days but that’s not a big deal for me. It only takes about 30 minutes to charge so I can just do it while I shower. I only wish I had spent more and gotten the Ignite with the built-in GPS. I didn’t think I would want that feature until last night during my team’s dragonboat practice. I needed to have my phone on me to connect to its GPS and I don’t like having my phone on the boat for fear of it getting wet. It tracked every moment, and I could go back and see the time, speed, heart rate and distance of every part of the practice on the map. Way freaking cool!! Oh whatever complaints people had about screen delays, they must have worked that out because I haven’t had that problem.

5.0 out of 5 stars Better than Fitbit Charge 4
Reviewed in the United States on July 24, 2020
I recently bought the FitBit Charge 4 for my wife and I as soon as it was released a few months ago. It was so sporadic with the GPS and was more of a entertainment device than actually helping me improve my health and wellness. She enjoyed the simplicity of it but even the steps were so off that it wasn't worth keeping.

I was researching the Unite and Ignite but ultimately decided on the Unite since it was cheaper and when I do run outside I always have my phone on me for connected GPS.. The fitness metrics and heart rate are extremely accurate and the recommendations on my daily workouts with the FitSpark feature are worth their weight in gold.

This is probably the lightest watch I have ever worn and I haven't taken it off since I got it. It is pretty stylish with a full color touch screen which has already been mistaken for an Apple Watch by a few people. The charging port is pretty unique as it clips right back into the watch and then you plug it in via USB. I also purchased a separate wrist band for this (as they are interchangeable) for when I am going out rather than having a sweaty band on me.

I am pretty happy with this so far - my treadmill workouts have been pretty accurate and the HR is spot on.
