Why Your Device Matters

The right device unlocks deeper insights about your body's patterns.

More Data, Better Patterns

Richer biometric data from your device means VitalWhy can detect subtler shifts in your health — like how a food sensitivity affects your HRV 6 hours later.

Health Connect Powers Everything

All of these devices sync their data through Android's Health Connect platform, which VitalWhy reads automatically. One integration, dozens of devices.

Continuous HRV Is Critical

Most wearables only measure HRV once per night during sleep. Garmin devices measure HRV throughout the day — letting VitalWhy detect how foods, substances, and stress affect you in real-time, not just at night.

⚠️ Limited Data: Nightly HRV Only

These popular wearables only share a single HRV reading from overnight sleep. While they have excellent sensors, they do NOT share continuous daytime HRV to Health Connect. This severely limits VitalWhy's ability to detect how daytime foods, substances, stress, and activities affect your body.

Nightly HRV Only ~$299+

Limited for VitalWhy. Despite excellent sensors, Oura only shares nightly HRV to Health Connect — a single sleep-time reading. VitalWhy cannot see how your afternoon coffee or evening meal affected your nervous system.
