How to Measure
PulseX Neo uses your camera to detect tiny changes in blood flow through your fingertip — the same principle as hospital pulse oximeters.
1
Open your camera page
Tap the heart icon in the bottom nav to go to the Home screen. You'll see the camera viewfinder.
2
Enable your torch / flashlight
The app tries to enable it automatically. If not, turn on your phone's flashlight manually — it acts as a constant light source for accurate readings.
3
Press fingertip over the lens
Place your index fingertip firmly over the rear camera lens. The viewfinder should turn red/dark. Don't press so hard your finger goes white.
4
Tap Start Scan & hold still
The 30-second countdown begins. Keep completely still — even breathing movements affect accuracy. The BPM will appear after ~5 seconds.
5
View your results
After 30 seconds, your heart rate, HRV, zone, and recovery score appear. Sessions are automatically saved to History.
💡 Tips for best accuracy
• Sit still and breathe normally during the scan
• Use in a dimly lit room (reduces ambient light noise)
• Measure at the same time each day for trend tracking
• Wait 5 minutes after exercise before measuring resting HR
• The signal quality bar should be above 50% for reliable results
• Use in a dimly lit room (reduces ambient light noise)
• Measure at the same time each day for trend tracking
• Wait 5 minutes after exercise before measuring resting HR
• The signal quality bar should be above 50% for reliable results
Accuracy Comparison
| Method | Accuracy |
|---|---|
| ECG (medical) | ±1 BPM |
| Chest strap (Polar H10) | ±2 BPM |
| Apple Watch optical | ±3–5 BPM |
| Fingertip pulse oximeter | ±2–3 BPM |
| PulseX Neo (camera PPG) | ±5–10 BPM |
Understanding Your Metrics
Heart Rate (BPM)
Beats per minute. Resting: 60–100 normal. Athletes often 40–60. Elevated at rest may indicate stress, dehydration, or illness.
HRV (Heart Rate Variability)
Variation in time between beats (RMSSD method). Higher = better recovery and parasympathetic nervous system activity. Typical: 20–80ms.
Recovery Score
Composite of HRV and resting heart rate. 75+ = ready to train. 50–74 = light activity. Below 50 = rest day recommended.
