VitalWhy works best with Garmin watches — they provide continuous HRV data throughout the day, not just a single nightly reading. Most other wearables only share sleep-time HRV, severely limiting pattern detection.
The right device unlocks deeper insights about your body's 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.
All of these devices sync their data through Android's Health Connect platform, which VitalWhy reads automatically. One integration, dozens of devices.
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.

Garmin is our only recommended wearable brand. Their watches measure HRV continuously throughout the day via their stress tracking feature, and share this data to Health Connect. This gives VitalWhy the granular data needed to detect how foods, substances, and activities affect your body — not just during sleep, but all day long.
⚠️ Why Most Wearables Fall Short: Devices like Oura Ring, Whoop, Samsung Galaxy Watch, Fitbit, and Apple Watch only measure HRV once per night during sleep. This "nightly HRV" approach means VitalWhy can only see how you recovered overnight — not how a 2pm coffee, evening alcohol, or stressful meeting affected your nervous system. For real pattern detection, you need continuous HRV data, which only Garmin provides via Health Connect.
Our top recommendation. All-day stress tracking measures HRV continuously, and this data syncs to Health Connect. VitalWhy receives HR, HRV, SpO2, skin temp, respiratory rate, and sleep stages — the most complete daytime HRV data available.

Budget-friendly fitness band with all-day stress tracking. The most affordable way to get continuous HRV data into VitalWhy.
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.
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.
Limited for VitalWhy. Whoop measures HRV continuously but only shares the morning "recovery" HRV reading to Health Connect. Daytime strain and HRV data stays locked in the Whoop ecosystem.
Limited for VitalWhy. Google's Fitbit ecosystem only shares sleep-time HRV to Health Connect. Despite continuous heart rate tracking, daytime HRV is not available for pattern detection.
Limited for VitalWhy. Medical-grade sensors but only shares nightly HRV. Excellent for ECG and blood oxygen, but daytime HRV patterns are not available.
⚠️ All smart rings only share nightly HRV data. None of them provide continuous daytime HRV to Health Connect, severely limiting VitalWhy's pattern detection. If you already own one, it will work for basic tracking, but we recommend a Garmin watch for comprehensive health insights.
Limited for VitalWhy. Shares nightly HRV only. Measures HRV during sleep but daytime readings stay locked in the Ultrahuman app.
Limited for VitalWhy. Good sensors but only shares sleep-time HRV to Health Connect. Cannot track daytime food or substance impact.
