Manual Measurement

You can trigger an immediate data fetch from Apple Health at any time.

How to Take a Manual Reading

1. Open StressMonitor on your iPhone
2. Tap the refresh icon on the Dashboard
3. The app fetches the latest HRV and heart rate samples from Apple Health
4. Your stress score updates within a few seconds

What Manual Measurement Does

Manual measurement reads the most recent samples stored in Apple Health — it does not instruct Apple Watch to take a new sensor reading. If Apple Watch has not collected new data recently, the reading reflects the most recent available sample.

When to Use It

• After waking from sleep (fresh overnight HRV available)
• After a period of rest or meditation
• When the automatic background refresh feels stale

Accuracy Note

For the most accurate stress assessment, measure after at least 5 minutes of rest. Physical activity immediately before checking will temporarily elevate heart rate and may not reflect your baseline state.
