  • Works well, but not a good sleep tracker
Color: Black
This product is great at tracking heart rate and activity, but if you lay awake in bed, it shows you sleeping.

  • Several QOL Issues with this Watch
Color: Black
I've done Garmin, I've done FITBIT. I want FITBIT's sleep tracking in a Garmin Watch, to be frank, mainly for the ability to use a heart rate chest strap. I've now tried POLAR. I may be wrong on the following, but after digging I've found; There is only one alarm on this watch. You cannot program it for specific days, only Everyday, Mon-Friday, Weekend. The battery drains very fast. Even charging it during the daily shower isn't enough to keep it going. You can export workouts to Strava, but you cannot import Workouts from Strava like you can with Fitbit. This is important to me because I have a Wahoo bike computer that I would like to pull to my Polar account, after exporting it to Strava. With Fitbit, I can pull that data from Strava to show that workout in Fitbits App. It doesn't input heart rate scored from my chest strap, however. Yet, my Fitbit Charge 3, for whatever reason compared to weight lifting or running, is almost spot on with the chest strap for heart rate on the bicycle. You cannot track your weight via the Polar App. You cannot input your weight from within the Polar App. On Apple, you hold your finger on the Polar App button and you can enter your weight. On the Polar website under Reports and Daily Activity, you can track your weight. Polar does not have a wifi scale in production that will log your weight for you. I have a Fitbit scale that uploads my weight, and I have to do nothing but step on the scale. There is apparently a third party program you can subscribe to for 2 dollars a month that will move your weight data from Fitbit into Polar's website. Again, this weight data can only be viewed from Polar's website. Sleep tracking is OK. This model is not capable of what is, I think called, Advanced Sleep Tracking. I miss my FitBit's ability to tell me of Apnea Attacks. This Polar will also think you are still asleep after you get out of bed to get a coffee and look at the inter net news before getting ready for work. It will add several minutes to "interruptions" for your sleep during this time and throw off the entire data package. You cannot edit your sleep time, at least from the app, maybe you can from the website but that is hardly worth the effort. Garmin never gets my sleep right. The Polar App has so much sleep data that it is perhaps too much data. I like how the numbers are large on the watch face, the Charge 3 is hard to read. Sometimes the Polar does not forward notifications from my phone. If that happens on the Charge 3, I just reboot the Charge 3. I haven't come up with a for sure way to make the Polar smart again. The face of the Polar has little in the way of customization. The Polar does not track steps, so much as "activity." You cannot tap the screen to turn the display on. You must either push the button or raise the watch. Raising the watch is almost flawless from the standing position, but while sitting, or if your arms are in front of you, typing this review for example, and you "raise the watch" it will not come on. I still haven't found what I'm looking for. ... show more

  • Better than expected.
Color: Black
I have used 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 advise to new users is the play around with it and read the manual to figure out what it can do. 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 its just one more thing I have to figure out. I do like how you can customize your training preferences and change the views for your workouts on your watch; exp WALKING I changed the view so that I 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 only major thing I despise is that there is a significant delay to turn 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. The face size is a little big 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! The pros definiently surpass the cons. ... show more

  • The Watch Does Give Heart Rate and Sleep Feedback
Color: Black
I like the watch and the constant heart rate feedback. I like the sleep feedback as well. I wish it had longer battery life. Also, doesn't slide from one face to another as easy as expected. Happy with purchase.

  • Overall, a great hr monitor.
Color: Black
I feel like my old Polar with a chest strap was a little more accurate, but the convenience of this makes up for it. The gos distance is a little short mountain biking, but that's more likely the ping rate of my phone. I wish it was easier to keep the display on the entire time of my work out. Overall, though, I think this is a great hr monitor. ... show more

  • I really love this fitness watch
Color: Black
I have had an Apple Watch for years. I have never liked having my phone activity connected to my watch. I really only wanted it for the fitness piece. I decided to change to the Polar Unite and I am glad I did. First, I love the round face. I think it looks more contemporary. It is also very light weight. I don’t even notice I am wearing it. The tracking seems to be accurate. It records activity, exercise, heart rate, and sleep. The reason I didn’t give it a 5 star rating is because there are a couple of things that are mildly annoying. One is that it doesn’t automatically sync with the app on your phone. You need to manually sync it if you want to look at your results on your phone (and it is significantly easier to look at it on your phone than on your wrist.) Second, the watch strap is a bugger the first time you try to buckle it. The strap is light weight rubber and the holes that you need to attach the other side are very stiff. After you secure it a couple times it is fine. The strap also makes me sweaty under it. I need to see if they sell alternate straps. ... show more
