I couldn’t find a simple app to help people measure blood pressure correctly, so I created one with Perplexity and Gemini: bloodpressure-app.netlify.app. Bookmark or share menu adds to Home Screen. For educational purposes only. Covers proper positioning, cuff placement, timing, and common mistakes.
