150: Active Minutes turns your heart rate into one simple weekly goal — your intensity minutes. The World Health Organization recommends adults get 150 to 300 minutes of moderate-to-vigorous activity every week. 150 makes hitting that goal effortless: using your Apple Watch heart-rate data, it counts your active minutes — also known as intensity minutes — minute by minute. Moderate minutes count once, vigorous minutes count double, all adding up toward your weekly target of 150. No clutter. No accounts. Just your intensity minutes, at a glance. WHY INTENSITY MINUTES? Steps don't tell the whole story. Intensity minutes reflect how hard your heart is actually working — the same kind of measure the WHO uses to define a genuinely active week. Reach 150 a week to stay on track, or push toward 300 for even greater benefit. FEATURES • A weekly ring that fills with your intensity minutes as you move • Moderate vs. vigorous intensity, calculated from your heart-rate reserve • Live intensity-minute counting during workouts on Apple Watch • Home Screen and Lock Screen widgets, plus a Watch complication • A per-day breakdown of your intensity minutes across the week • A clean, focused design that gets out of your way PRIVACY FIRST 150 reads your heart-rate data on your device and never sends it anywhere. No servers. No tracking. No ads. Ever. 150 PRO (optional) Unlock extra themes, ring styles, and intensity-minute history trends with a single one-time purchase. The core weekly goal is free, forever — no subscriptions. Hit 150 intensity minutes by the end of the week.

Verdict

The call

The clearest difference is in-app purchases: Grace and Gravity Studio at none against 150's 1. Grace and Gravity Studio also leads on iOS requirement (14.0 vs 16.0). 150's advantage is ads (none vs shown) and update cadence (every 2 days vs every 2 months). On price and device support there is nothing between them.
