Store description excerpt

Pulse Monitor is a clear, science-minded app for pulse, heart rate variability (HRV), breathing, and recovery trends on Android. Use the camera for pulse and HRV sessions, and motion sensors for breathing sessions. Measurements are processed on device, with no required account. Built for people who want useful physiology trends without hype: - No subscriptions - No ads - No required account - On-device processing - No cloud dependency for calculations PULSE & HRV (camera PPG) From a fingertip camera signal, Pulse Monitor estimates: - Pulse (BPM) - AVNN, CVNN - RMSSD, SDNN, SDSD - NN20, pNN20, pNN50 - TRP (irregularity index), SampEn, Shannon entropy - SD1/SD2 ratio, Poincare area - HF, LF, VLF, Total Power, LF/HF - Baevsky Stress Index BREATHING (motion sensors) With the phone placed on the abdomen, Pulse Monitor estimates: - Respiratory rate - Mean breath interval - Breath-interval SD - Breath RMSSD - Breathing CV - Breathing amplitude CV GUIDED TESTS Pulse tests: - Squat CRF Test (Ruffier-Dickson, Ruffier, HRR1, load reaction, recovery index, VO2max absolute/relative) - Active Stand Test (delta HR, stand ratio, stand slope) - Deep Breathing 6/min Test (E:I ratio, I-E difference, RMSSD) Breathing tests: - RR Recovery Test (recovery time, delta RR) - Paced Breathing 6/min Test (error to target, compliance, breathing quality) BREATHING PROTOCOLS - Guided breathing protocols with stage timers and safety notes - Clear protocol names in the main list, with detailed purpose and safety notes inside each protocol QUALITY-FIRST MEASUREMENT LOGIC - Strict contact and motion checks - Early quality gate plus continuous quality validation - Automatic rejection of unreliable sessions instead of misleading numbers - Clear messages when signal quality is insufficient TRACKING, HISTORY, SHARING - Measurement history with tags - Detailed report cards for pulse, breathing, and tests - Shareable result cards APP INTERFACE - Current UI languages: English and Russian. IMPORTANT DEVICE NOTES Requires a compatible Android phone with a working camera/flash for pulse measurements and motion sensors for breathing features. Feature availability and signal quality may vary by device model, camera, flash, and sensors. IMPORTANT HEALTH NOTICE Pulse Monitor is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, diagnosis, or treatment. Do not use the app for emergencies. Pulse Monitor does not measure and does not claim to measure: - Blood pressure - Blood glucose - Medical-grade SpO2 - Lung volume - ECG intervals (PR/QRS/QT) - Cardiac output
