No, I’m not wearing them all on my right wrist, but I had to for the pic.

Long story short, a couple of months ago I got my hands on a Polar 360. This was before Polar announced their September release and before the Helio Strap was revealed. I’m a software engineer, and since Polar open-sourced th...

The app kept telling me to 'pay attention', but I felt fine so I put it down to bad data from the sensor...

Hey All!

After a lot of feedback, critiques and trialling, I have built upon the "Original" and "Popular" adapter that I Previously Released!

I will shortly be releasing the model for free, for you to print yourselves at home! 100% Authentic original design that has evolved over countless iteratio...
