PakBill: Pakistan Bill Checker

Project overview

PakBill is a React Native app built with Expo, backed by a Node.js service hosted on my home server in Pakistan. The server calls government utility APIs so requests originate from within Pakistan. The app fetches bills, breaks down each charge, and keeps bill history on-device for offline access, with support for multiple connections and due-date tracking.
