Why 15 Seconds Beats 15 Minutes of Tracking
Over 80% of health app downloads are abandoned after two weeks. The cause is always the same: high cognitive load. When an app demands logging every gram of food, typing journal entries, or navigating complex sub-menus, the human brain rejects the friction.
Sub-15s single-tap inputs eliminate logging resistance and decision fatigue.
Visual momentum builds neurochemical habit loops, cementing automaticity within 66 days.
Protects key physiological buffers: VO2 Max, grip strength, restorative sleep, and metabolic autophagy.
