I used this field on my 935 to compare different sources of HR - it gave me confidence in my TICKR FIT, and helped me decide when the wrist oHR would be 'good enough'.
However.... its not listed on the CIQ site as compatible with the 945. Does anyone know of an alternative, or know if its possible to 'sideload' direct in the apps folder and could point me at somewhere to download the right file ?
