I built a Blood Pressure tracker because I was tired of the existing apps requiring cloud accounts, subscriptions, or selling health data to advertisers.

BP Tracker Pro is a "Class I Data Logger" built with Capacitor and Vanilla JS. It runs 100% offline on your device.

Key Features: - Gorgeous panel to visually track your blood pressure readings - Zero Cloud Sync: Data lives in a local JSON store (encrypted at rest by Android OS). You can bacjup - PDF Reports: Generates clinical reports for doctors using jsPDF (client-side). - Morning Surge Detection: Analyzes AM vs PM readings to flag stroke risks. - Family Mode: Track multiple profiles (e.g., aging parents) from one dashboard.

Tech Stack: - Vanilla JS + Vite (No React/Vue overhead) - Capacitor v8 (Bridge to Native) - Chart.js for trends
