150 Min

150 Min tells you if you're getting enough exercise using data your Apple Watch already collects. No workouts to log. No buttons to press. No streaks.

Research shows 150 minutes of vigorous activity per week reduces all-cause mortality by 20%. 150 Min tracks your progress toward that target automatically, using heart rate data from HealthKit.

What it does:
- Classifies every minute as rest, moderate, or vigorous based on your personal heart rate range
- Learns your sleeping heart rate and max heart rate over time — no setup required
- Shows weekly effective minutes with a daily breakdown
- Tracks sleep duration, regularity, and stage composition
- Estimates VO2max from your heart rate range with age-group percentiles
- Lets you drill into any day to see your heart rate timeline and activity bouts

What it doesn't do:
- Collect or send your data anywhere
- Require an account
- Gamify your health with streaks or badges
- Tell you what to do

Your data stays on your device. There are no analytics, no cloud sync, and no ads.
