A health-tracking Android app for logging blood pressure, oxygen, pulse, glucose and
weight — designed for elderly users first. Oversized one-digit-at-a-time keypad,
high-contrast readings, and a one-tap printable report their doctor can actually read.
Medication list that keeps withdrawn drugs visible in red instead of hiding them, so
nobody takes one by mistake.
Offline-first: the database lives on the device and never leaves it unless the user
syncs it to their own LAN server. Built with Expo/React Native in strict TypeScript
across 15 languages, with speech input, a marketing site in Astro on Cloudflare Pages
behind a hash-pinned CSP, and a Hono + SQLite sync server with last-write-wins
reconciliation.
