StayFit app

StayFit app sehr gutes Programm aus Marco Altini

Release-Datum 9 years ago 1.1.6 version.
StayFit is the first app able to quantify your fitness level by providing a new and unique biomarker, the Fitness Index. Using only your phones camera and motion sensor, StayFit can acquire your heart rate and physical activity levels with high accuracy, and combine all these parameters to provide you with a key indicator of your physical condition, the Fitness Index

The Fitness Index is a proxy to your cardiorespiratory endurance, one the most important determinants of physical fitness, health and wellbeing. A unique biomarker that does not depend on your age or body size, but only on your physiology and behavior

HOW DOES StayFit WORKS?
State of the art research showed that combining anthropometric data (i.e. your height, weight, age and sex), together with your physical activity level and heart rate can provide accurate cardiorespiratory endurance estimation, without the need for laboratory tests. This is the principle behind StayFit and the Fitness Index

StayFit further adapts the Fitness Index to your anthropometrics data (e.g. weight, sex, etc.) to provide a unique biomarker which is not affected by those parameters, aiming at determining your actual physical fitness beyond what current tests can do
