Based on a technology analysis, it does not seem that the Apple Watch would be able to gather accurate enough heart rate data to be able to arrive into meaningful analytics for the user - if the input data is so-so, the output will not be very accurate either. Mechanical design, optimal fit, sensor layout are all things that are so important for being able to extract accurate optical heart rate and when you seek to do 20 things at the same time, you will have to compromise on something. Same thing with the Samsung Gear Fit that occasionally manages to capture a resting heart rate reading.
So in short, we are targeting a very focused sports heart rate monitoring market where optimal performance during sports is at the core and we have the most accurate and reliable optical heart rate sensor and device design for that. It could be said that smart watches in general are more targeted to the wider tech audience whereas sports/fitness enthusiasts will be foremost looking for a dedicated solution.
