PulseX Neo
v3.2 · Real PPG Engine
Clinical-grade heart rate monitoring using only your smartphone camera
PulseX Neo uses photoplethysmography (PPG) — the same optical technology found in hospital pulse oximeters — to measure your real heart rate without any wearable device.

How PulseX Neo Works
Uses your phone's rear camera to detect microscopic changes in blood colour through your fingertip — no wearable needed.
Step-by-Step Measurement
1
Go to the Scan screen
Tap the ♥ Scan button in the bottom navigation bar. Make sure you're in a quiet place and sitting comfortably.
2
Enable the torch / flashlight
PulseX Neo tries to turn on your rear flash automatically when you start a scan. If it doesn't activate, manually switch on your phone's flashlight — the light is essential for detecting your pulse.
⚠️ Without the torch, readings will be inaccurate or unavailable.
3
Cover the lens with your fingertip
Place the pad of your index finger gently but firmly over the rear camera lens. The viewfinder should go dark red or near-black. Your finger should cover the lens completely — no gaps.
✅
Correct
Whole pad over lens, gentle pressure
❌
Avoid
Fingernail, gaps, or pressing too hard
4
Tap Start Scan — then hold perfectly still
The countdown begins (default: 30 seconds). Your BPM reading will appear after about 5–8 seconds. Keep your hand, arm, and body as still as possible — any movement degrades the signal.
📊 SIGNAL QUALITY BAR
Watch the signal quality bar below the viewfinder. Aim for 40% or higher before trusting your results. If it stays low, reposition your finger and press more firmly.
5
View and save your results
When the scan finishes, your results appear automatically — heart rate, HRV, heart rate zone, recovery score, and estimated calories. Add a mood tag and note, then tap Save & Continue.
Understanding Your Results
Heart Rate (BPM)
Beats per minute. Normal resting range is 60–100 BPM. Athletes may sit 40–60. Consistently above 100 at rest warrants a doctor visit.
HRV — Heart Rate Variability (ms)
The millisecond variation between heartbeats. Higher is generally better — it means your nervous system is adaptable and you're well-recovered. Values vary widely by age; track your own trend rather than comparing to population averages.
Recovery Score (0–100)
A composite score based on your HRV and resting HR. 75+ = ready to train. 50–74 = light activity only. Below 50 = prioritise rest and sleep tonight.
Heart Rate Zones
REST <60 · EASY 60–69 · FIT 70–84 · HARD 85–99 · PEAK 100+. These are resting HR zones, not exercise zones — a resting PEAK reading indicates elevated stress or post-exercise elevation.
Tips for Best Accuracy
🕐
Measure at the same time each day
First thing in the morning, before coffee or exercise, gives the most consistent baseline.
🧘
Rest 5 minutes before scanning
Sit down, breathe normally. Even a short walk will temporarily elevate your reading.
💧
Stay hydrated
Dehydration reduces blood volume and can raise resting heart rate by 5–10 BPM.
🌑
Scan in a dimly lit room
Bright ambient light leaking around your finger interferes with the PPG signal.
🚫
Avoid immediately after exercise, caffeine, or stress
These all temporarily elevate HR and lower HRV, making resting comparisons misleading.
📈
Track trends, not single readings
One scan means little. 7+ days of data reveals meaningful patterns in your cardiovascular health.
⚕️ Medical Disclaimer
PulseX Neo uses camera photoplethysmography (PPG) — the same optical sensing principle used in most wrist wearables. It is designed for wellness tracking only, not medical diagnosis. Results can be affected by skin tone, ambient light, finger pressure, and movement. Always consult a qualified healthcare professional for medical concerns.
Common Questions
Why does BPM take a few seconds to appear?
The algorithm needs at least 5–8 seconds of clean PPG signal to calculate a reliable heart rate. The live trend chart will begin showing data as soon as detection is confident.
My BPM reading seems too high or too low — why?
Check that your finger fully covers the lens with no gaps and the torch is active. Use the Calibration offset in Settings if your readings are consistently off by a fixed amount compared to a reference device.
What is HRV and why does it fluctuate so much?
HRV naturally varies day to day based on sleep quality, stress, alcohol, illness, and training load. Short-term (30s) HRV is less stable than 5-minute clinical readings — use your 7-day rolling average as a baseline rather than individual values.
Does this work on all phones?
PulseX Neo works on any modern smartphone with a rear camera and flash. Performance is best on phones with high-quality sensors. Some budget devices with heavily processed camera pipelines may produce noisier signals.
