Daniel

The watch meets all my requirements and more. The guided exercises are really good and the associated app is very clear. The delivery was quicker than expected. However, if you want good GPS tracking, this watch will not be quite the right one. I don't need this function so I still give it five stars.

Good basic watch for running and fitness. Good vibration response. Good design. Live is better than in the photo. The only negative is that it loses connection with the phone and sometimes does not want to synchronize (of course, the problem may also be in the phone).

It was a challenge to put the Unite on in the first place! The straps are poorly designed. But once you get the hang of it, its fastened securely. Reads all vitals really well and together with the Polar mobile all and Web Service, you'll have all the data you need to track your health and fitness. Polar's ecosystem rocks!

Giovanna

is it compatible with Polar OH1+OHR heart rate sensor, does it provide the possibility to read the arm sensor measurements directly on the sports watch without the presence of the smartphone?

Answer of Alfonso

I can´t guarantee this 100%, but based on the knowledge I have gained from almost a year of using this watch, I don´t think what you´re saying is possible. While it´s a good watch, it´s quite basic and requires support from your phone for GPS and the app to send its data. I think it´s designed to send data to your phone, not to receive it from other measuring devices. The band can send its data to your phone or a bike computer, for example. But I don´t think the watch can receive data from the band. That band probably uses +Ant communication to transmit its data, and the watch doesn´t recognize that technology.

Answer of Annemarie

Regarding question 2: The values on the watch are easy to read. I don´t use the heart rate sensor. I´m very happy with the watch!
