VerveVerveVerve measures MET-hours and cardiorespiratory fitness — the same metrics used to assess mortality risk in peer-reviewed research — with every threshold in the app traced to a cited source.
Six pillars, each backed by named, checkable research — not a proprietary score nobody can audit.
Moderate-to-vigorous minutes climb against WHO, personal, and AHA altitude lines — a flag plants the moment you cross each one. No ring, no streak to break.
Cooper, 1.5-mile run, Rockport walk, CPET and more — classified against ACSM/Cooper norms under 40, Cleveland Clinic treadmill data (Mandsager 2018) at 40 and over.
Karvonen heart-rate-reserve zones computed from your age, resting HR, and fitness — not a fixed 220-minus-age formula.
Screening bands from ESC/EAS, NCEP ATP III, and AHA/CDC guidelines — every threshold traced to its source, none of it a treatment target.
Metabolic syndrome screening (Alberti 2009) alongside a 6-test functional battery — grip, balance, chair stand, gait speed, and SPPB.
Two bars, one sentence — no percentage, no black-box score, no comparison to anyone but you.
No proprietary "recovery" or "strain" score you can't check the math on — every threshold links to the paper it came from.
