  • ”1 week in, and I love it. Sent my Fitbit Charge 4 back after the 1st day! Everything about the Unite is superior to the Fitbit. The lack of built-in GPS is a nonfactor for me as I always have my phone with me. The continuous HR seems to be flawless, and I have no issues with it registering the sleep tracking. I always had issues with the Fitbit not showing my heart rate and had a couple of nights not registering sleep. Polar Flow is an awesome app and has easily replaced Run Keeper. The only thing keeping this form 5 stars is the band. Although the band is very comfortable, it is a huge pain in the butt to put on and adjust. A traditional silicone metal buckle strap like on the ignite would be much better. With a $35 price tag, that is a tough pill to swallow. 4 out of 5 isn’t bad, and the 1 star has nothing to do with function, as the function is flawless.”

  • ”I have used the Polar HRM (chest strap) for many years and finally got tired of the straps not working, so I decided to try this watch, and I am glad that I did! There’s a lot to learn about this watch and all of its functionalities, and my advice to new users is the play around with it and read the manual to figure out what it can do… I like how you can customize your training preferences and change the views for your workouts on your watch; exp WALKING, I changed the view to see calories, HR, time, and distance. You can only make those changes on flow – this is actually an awesome feature now that I think about it. You can also delete and add workouts. The watch seems pretty spot on in terms of accuracy…The face size is a little bit since my wrist is so small, but then I guess if it were any smaller, one might have a hard time reading the text. Not a big deal. Not sure I will use this watch as a fashion watch because of that, but now that it calculates step, I have to say I have gotten addicted to surpassing prior days’ numbers, so I will have to wear the watch in order to do that. All in all, the watch is a great buy!”

”Really do like this watch and would buy another if it gets broken.

BTW it comes with two watch bands which are easy to change out. I was afraid it would be a one size fits all kind of deal, which never fits my wrists, pleasantly surprised by how easy it was to swap the band over to the larger size.”


4.0 out of 5 stars Decent Polar Watch, with a few minor flaws

” The downside is the battery life is pretty poor.

Once or twice, the screen was stuck blank, and had to reboot the watch.

The app likes to be fussy about connecting to sync data.

A couple of times, it didn’t have good skin contact and was reading the heart rate wrong, but that was more me learning to use the band correctly.

The biggest complaint is the charger. Rather anything else but this flimsy charger. Which tonight decided to melt. I’m hoping the replacement charger gets here before the battery level becomes critical.”

  • ”It’s pretty easy to use, but you have to set it up on polar flow first. I originally just set up the watch and then downloaded the app, and the watch and app were not syncing, then I figured out that polar flow has to be used regardless. Even though the manual says you can set up the watch on the watch- you can’t. So now I have the watch, the app, and polar flow, and when you sync all 3, at times, you will get different readings on all three. That is annoying. Not sure why you need the app and flow. Yes, flow is more detailed than the app and perhaps even better to read, but it’s just one more thing I have to figure out….The only major thing I despise is that there is a significant delay in turning on the watch from its resting point. I find I have to raise my arm multiple times to get it to wake up. Another thing I don’t like is that there is a delay when it calculates your calories during your workout. Again I have to move my arm up and down several times to get it to update, and that is a pain. All in all, the pros outweigh the cons. It is a great buy!!”



The Polar Unite Fitness Watch is a great buy if you are looking for something that is not too expensive that does the job for most people. My grade for this watch is a 4.0 out of 5.0 because of how many apps you have to download, and it’s sometimes funky to sync to your watch.
