OxyScore: VO2max & Fitness Age

New: a Strength tab beside your VO2max. Keep your own strength log, reps and weight, and walk into the gym knowing the weight to beat.

Two things you can train are tied to a longer life: your VO2max, the fitness measure most linked to longevity, and your strength. OxyScore keeps both in one place. Measure your VO2max properly, train it on your wrist, and keep the record of what you lift beside it.

MEASURE IT PROPERLY Three guided field tests — Cooper, Rockport walk and an indoor max effort — turn one real effort into a measured VO2max, with its accuracy range and the study behind it shown in the app.

SEE WHAT IT MEANS • Fitness age — the age your VO2max says you are — with your percentile (FRIEND registry) • Your fitness category, from a 122,007-person study (Mandsager 2018) • Heart-rate recovery, resting heart rate and HRV, never blended into a score

TRAIN IT ON APPLE WATCH Five cited protocols — Norwegian 4×4, VO2max 4×3, 10-20-30, Billat 30-30 and Zone 2 — coached live on your wrist with haptic cues. A hard interval asks for at least 90% of your max heart rate — a floor to reach, not a cap. Your numbers show on iPhone; guided sessions need Apple Watch.

STRENGTH, THE OTHER HALF Strength training is associated with lower all-cause mortality, and the largest association of all is for people who do it alongside aerobic training (Momma 2022). Keep your own exercise list and log reps and weight. Every exercise shows your last session's top set, your estimated max and whether it moved, so you arrive knowing the weight to beat. A record you keep, not a score the app awards.

YOUR WEEK, PLANNED FOR YOU One adaptive weekly goal, sized to your fitness, stepping up when you're ready; a rough week gets a real deload. On supported iPhones, Apple Intelligence writes it from verified numbers.

IT COMPOUNDS Weekly streaks, 34 achievements, a training level only real work moves, monthly Longevity Reports.

PRIVATE BY DESIGN Your health data never leaves your devices. No accounts, no tracking, no analytics — everything computes on-device from Apple Health, where workouts save back.
