So many people invested a lot of time in Android Apps for sports sensors, like Rainer Blind, Max Candocia, Jukka Happonen. Some projects are given up, and not developed further. People invest time in writing papers about the Polar OH1 or conference papers about the Garmin Venu SQ, until Polar changes the running time of the Verity Sense by a software update, or Garmin changes the heart rate accuracy of the Venu SQ by a software update. Choosing these devices for writing papers is a waste of time. It is better to choose hardware components like DF robot optical sensors or OpenBCI Cython boards combined with newly available updated WIFI shields from Aliexpress, which are not controlled so much by the developer.
It is also a pity that we have so many options for ECG with Bitalino, but then we want the most accurate heart rate from a 3 lead ECG which is only available as an example from OpenBCI. But are there any ECG toolboxes for OpenBCI? There are many, there are toolboxes in Matlab, HeartPy in Python, but do they work with OpenBCI?
The Polar H10 is an ECG device, and the Apple watch an optical heart rate sensors. Rob ter Horst invests a huge effort in testing every new sports watch. But is this not a waste of time as well? Is it not better do develop an open source sports watch and an open source ECG device which is sustainable and which is so accurate, that it does not require accuracy test after accuracy test after accuracy test?
