ARM 1:

N1\~ 3'300 subjects.

Research participants are Aktiia G1 users with Android operating system, i.e. individuals who already purchased the Aktiia G1 device out of the context of the study, located in Switzerland, Germany or UK, and owning a smartphone with Android operating system. ARM 1 research participants are asked to:

* For the next 10 years: wear their 24/7 Aktiia G1 device continuously as they would outside the context of the research project, * For the next 10 years, starting at their inclusion in the research project and every 6 months thereafter: fill in an online survey on their lifestyle- health- socioeconomic environment. * Additionally, once the Aktiia One App is released and for the next 10 years: * Take an on-demand measurement with the Aktiia G2C feature (finger measurement) while seated.

ARM 2:

N2\~ 6'600 subjects.

Research participants are Aktiia G1 users with iOS operating system, i.e. individuals who already purchased the Aktiia G1 device out of the context of the study, located in Switzerland, Germany or UK, and owning a smartphone with iOS operating system. ARM 2 research participants are asked to:

* For the next 10 years: wear their 24/7 Aktiia G1 device continuously as they would outside the context of the research project, * For the next 10 years, starting at their inclusion in the research project and every 6 months thereafter: fill in an online survey on their lifestyle- health- socioeconomic environment. The completion of a survey lasts 5min maximum. * Additionally, once the Aktiia One App is released and for the next 10 years: * Take an on-demand measurement with the Aktiia G2C feature (finger measurement) while seated.

ARM 3:

N3\~ 5'000 subjects.

Research participants are non-Aktiia-G1 users (they do not own an Aktiia G1 device at their inclusion in the study), located in Switzerland, Germany or UK, and owning a smartphone with either iOS or Android operating system. ARM 3 research participants are asked to:

* For the next 10 years, starting at their inclusion in the research project and every 6 months thereafter: fill in an online survey on their lifestyle- health- socioeconomic environment. The completion of a survey lasts 5min maximum. * At their inclusion in the study: download the Aktiia One App to access G2C functionality with on-demand measurements at fingertip using the smartphone's camera. * For the next 10 years, starting at their inclusion in the research project and thereafter:
