Five short, validated functional-fitness tests — the 30-second chair stand, single-leg stance, 4-meter gait speed, Timed Up & Go, and grip strength — each scored against published research norms for your age and sex, not marketing copy.
Everything runs on your device. An optional on-device camera can count chair-stand reps for you; no video is ever recorded, stored, or transmitted, and manual entry always works if you'd rather skip the camera.
