Pressure4U
Alexandre agopin
Pressure4U turns your iPhone’s rear camera and flash into a fingertip wellness scanner. Using photoplethysmography (PPG) and AI-assisted signal analysis, the app estimates heart rate, oxygenation trends, and blood-pressure trends in about a minute—no cuff required for a quick check. HOW IT WORKS • Place your fingertip over the rear camera that lights up with the flash • Follow the 5-second countdown, then hold still while Pressure4U reads your pulse wave • See heart rate (BPM), SpO₂-style oxygenation, and systolic/diastolic estimates • Optional cuff calibration learns a personal offset to better match your validated monitor DESIGNED FOR CLARITY • Live camera preview so you always know which lens to cover • Colorful, modern interface with glowing cards and clear results • History charts and saved readings for up to one year (stored on your device as JSON) • Globe language picker: English, Portuguese (Brazil), Spanish, French, German, Hindi, Simplified Chinese, Telugu, Ukrainian, Russian, Italian, Arabic, and Norwegian IMPORTANT — WELLNESS ONLY Pressure4U is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease. Camera-based blood pressure and oxygen estimates are approximations for personal wellness. Always consult a qualified clinician for health decisions, and use a clinically validated cuff or pulse oximeter when medical accuracy is required. Privacy-minded: measurements stay on your iPhone. Camera access is used only for fingertip scanning.
