How biological age is measured in Istanbul
fjt reads four signals from everyday life in Istanbul: steps and movement, sleep duration and regularity, perceived stress, and nutrition including alcohol and caffeine. These map onto established ageing markers and collapse into one score.
No wearable required — your phone is already with you, so measurement starts on day one and updates daily.
