Oura has refined its ring sensors across four generations. The Ring 4's flattened LED array delivers more accurate SpO2 and heart rate data than previous generations, especially during sleep.
Up to 8 days of continuous 24/7 tracking between charges in a ring that weighs as little as 4 grams. No screen to drain — just sensors running around the clock.
The Oura app supports iPhone and Android equally. Core health data syncs to Apple Health, Google Health Connect, and 40+ third-party fitness apps.
WHOOP 5.0 gives you a biological age score derived from your sleep, recovery, and training habits — showing whether your lifestyle is ageing you faster or slower than your years. Updated daily, it makes long-term health trends visible at a glance.
WHOOP's AI Coach learns your body's patterns and delivers personalised daily recommendations in plain language — not just what happened, but why, and what to do next. It adapts to your training load, sleep debt, and recovery trends.
WHOOP 5.0 added a dedicated strength trainer that auto-detects sets, measures neuromuscular load alongside cardiovascular strain, and shows recovery demand from resistance training — a gap every previous WHOOP version had.
The right pick depends on what you optimize for.

Health-focused wearers who want continuous biometric tracking without a watch on their wrist.

The subscription is optional but unlocks most of the app's value.
