150 Min
Know if you're getting enough exercise. No logging. No streaks. Just the truth from data you already have.

Research shows that 150 minutes of vigorous activity per week is the sweet spot for reducing all-cause mortality by 20-23%. That's just three 50-minute sessions. 150 Min tells you exactly where you stand — automatically, using heart rate data your Apple Watch is already collecting.
No workouts to log, no buttons to press. 150 Min reads your heart rate data from HealthKit and figures out the rest. It even works without workout mode.
Your weekly effective minutes — front and center. Vigorous minutes count fully, moderate minutes at half. See your progress toward 150 at a glance.
Duration, regularity, and stage breakdown from your watch's sleep data. Research shows sleep regularity is a stronger predictor of mortality than duration alone.
Your cardiorespiratory fitness estimated from sleeping and max heart rates — no treadmill test required. Tracked over time with age-group percentiles.
Wear your Apple Watch. It records your heart rate throughout the day — during workouts and in between.
150 Min learns your range. Your sleeping heart rate becomes the floor. Your highest sustained effort becomes the ceiling. No manual input needed.
Every minute is classified. Using a logarithmic model calibrated to exercise science, each minute of your day is mapped to rest, moderate, or vigorous activity.
See where you stand. Your weekly total, daily breakdown, sleep regularity, and fitness estimate — all derived from data you already have.
Every number in 150 Min traces back to published research. The 150-minute target comes from large-scale mortality studies. The heart rate model uses a logarithmic MET formula that matches real-world exercise intensities. The VO2max estimate uses the Uth et al. formula adjusted for age and BMI. Sleep regularity metrics are based on Windred et al. (2024), which showed regularity is a stronger mortality predictor than duration.
No proprietary algorithms. No gamification. Just science and your data.
150 Min reads from HealthKit and never sends your data anywhere. No accounts, no cloud sync, no analytics. The app runs entirely on your device.
