Description:
The xim Lifelight is a blood pressure app based on artificial intelligence. Although its blood pressure measurement technology has been evaluated, it is not possible to base a determination on its accuracy from this research. Blood pressure measurements are made, using AI, from a facial image. It is intended for self-measurement and home use.
Assessment:
The technology used in the xim Lifelight, to measure blood pressure, has been assessed, in a general population, according to a non-standard protocol.
Recommendations:
