- Since several years Peter Gamma from www.petergamma.org is interested in smartwatch accuracy tests.
- It started with the claim that optical heart rate monitors have become more accurate such as the Polar OH1 and accuracy validation papers about it which where published in PLOS ONE:
- Then we had accuracy studies about the Polar H10 performed at the Swiss Federal Institute of Sports in Magglingen.
- And we had validation studies about consumer grade heart rate monitors at the Cleveland Clinic in Ohio.
- But did these accuracy validators stop testing after they have published their scientific studies?
- And now we end up with only one single smartwatch accuracy tester who tests smartwatches only on YouTube:
- But we do not know of any other scientists which reproduce these data.
- But who uses smartwatches for scientific studies anyway?
- Who else than Peter H. Charlton, Biomedical Engineer specialising in signal processing for wearablesfrom the Universities of Cambridge and Oxford?:

- And now we have learned that for gold standard for heart rate measurements:
- A three lead (or 3 channel) ECG device.
- The Mason-Likar electrode placement.
- ECG-based HR has to be determined by visual assessment of a trained research personnel.
- Is necessary.
- But smartwatches as well as the Polar H10 do not fullfill these requirements.
- And sellers of products for scientific studies such as Biopac, iWorx offer only view PPG sensors.
- They mainly offer ECG devices with 3 channels and more
- As far as Peter Gamma from www.petergamma.org knows only view scientists use smartwatches for scientific studies.
- If we do not trust Rob ter Horst and his accuracy tests on YouTube, but we are still looking for affordable and accurate devices for measuring the heart rate:

Information for product sellers who do stock market speculation and scalping with the products mentioned by Peter Gamma on www.petergamma.org.
According to the little experience of Peter Gamma from www.petergamma.org, many of the products listed here are still full of issues which need to be resolved. If you do stock market speculation and sculping with those you will loose Peter Gamma from www.petergamma.org as a buyer of these products ans as a reviewer. Is this not risky? Will you not loose the majority of your costumers as well? And does society in general not accept stock market speculation and scalping with products as those which are listed here? And will you not be politically incapable of finding a majority of the voters if you do stock market speculation and sculping with the products listed here? And as a consequence will you not be condemned and punished by a political referendum soon? Especially if you do this to a Swiss, since are not majority of Swiss against stock market speculations and sculping with people on a budget? And people in Switzerland are known for a lot of political referendums, since we have direct democracy in this country. And Peter Gamma from www.petergamma.org will fight up to the European Court of Human Rights against people who do stock market speculation and sculping with the products which are listed under www.petergamma.org. And if they do not have yet the legal basis there, he will fight for it.
