Renka is the first iOS app using IR depth-sensing to measure your face in real-time. Unlike photo-based apps, Renka captures true 3D geometry using the same IR sensor that powers Face ID. Features: - Face measurement (width, height, area) - Golden ratio analysis - Symmetry scoring - Puffiness tracking - 100% on-device processing What's different: Most apps use ML on 2D photos. Renka processes 1,220 vertices in real-time for accurate results. Free 3-day trial.
