## Description

Review: Best fitness tracker that I've had and I've had quite a few - This is a nice easy to use tracker. I've had cheap and more expensive trackers and this to me is the best. I have had it now for 3 months. I replaced my Garmin Vivosmart4 with the Polar A370. It's so much more accurate. I can get more info on the tracker than I did on my Vivosmart4. After I had it for a while my Vivosmart4 had wildly inaccurate heart rate, stairs, step tracking. I contacted Vivosmart4 and upgraded firmware and it didn't fix it, so I bought the A370. I believe the A370 is quite accurate. When I first checked, it was quite accurate. Steps were possibly 5-10% off. I compared heart rate to a finger monitor and it was about the same. Exact accuracy is not a big concern for me. I use it to benchmark activity from day to day. The buttons to wake the device and to navigate are good - much better than my Vivosmart4. On the Vivosmart4 I could accidentally turn off my workout, or set something off if I rested my hands behind my back, or bumped it. I have a small wrist, 5 7/8 inches and was used to the small size of the Vivosmart4. I thought it might be too clunky, but it looks fine. Also, I can easily read it in sunlight (unlike the Vivosmart4). Some people mentioned that they had trouble connecting to their phone. It always connects for me. The A370 does not have stair tracking but that's not an issue for me. Also, some people mention the short battery charge. I do wish it were longer. However, I just plug it in when I shower, sitting eating dinner, or watching TV in bed at night. It usually isn't fully charged, but it doesn't run out of battery this way either. The band took a bit of getting used to it. If the elastic holders are further away from the buckle it's easier to get the strap into the elastic holders, but I would prefer a normal strap holder. I'm not a runner. I use it for daily activity, weight training, walking, stepper and low impact aerobics. The app is good - at least as good as others that I've used, and there is a web based app as well that's quite good.
Review: Great Tracker After Fiddling With It But Keeps Poor 24 Hour Clock Time. - You really need to read the manual for this. So too, as others mentioned, the Polar mobile app worked poorly for me (constantly re syncing) on my iPhone 6s , although it works fine on my Dell Desktop Computer running Widows 7. Setting it up thru the watch and app took some time but works fine now. To have it stay on continuously you need to press and hold with your finger above the calorie counter where the "flame" appears and then after a few seconds a "light bulb" will appear indicating the display is now on continuously. This setting is not retained after turning off the watch or exiting an exercise. Update: Question: What watch does not keep time? Answer: This A370 fitness watch. I left this watch off for a few weeks and lost over 5 hours of time on the clock. Big boo!!

### ⭐⭐⭐⭐ So far, so good!
*by R***S on June 19, 2019*

I plan to update this if I run into any issues. I’m just 6 hours into the Polar a370. I have a smaller wrist and the small fits perfect. I was expecting the band to be too long based on a few reviews I had read but it’s just right. When I first set it up, it was reading my resting heart rate as WAY higher than it was- it was 60 and the tracker was giving me 110. I was super disappointed but then I fully charged it and restarted it and the reading has been accurate since. It was accurate at resting and during a workout- I stopped and manually checked my pulse multiple times. I love the options for the clock face and I plan on changing it up frequently as my mood changes. I’m curious to see the battery life and will update if it is disappointing.
