I want to create a straightforward Financial Management application focused squarely on Expense Tracking and aimed at everyday, middle-class users who need a clean way to see where their money goes. The first release will be for Android. Core flow • A user opens the app and can instantly log a purchase in just a couple of taps—no complicated onboarding. • Entries are auto-grouped into categories (food, transport, bills, etc.) and shown in clear daily, weekly and monthly summaries. • Simple charts highlight spending trends; colour cues make overspending obvious. • Data lives locally first so the app works offline, but it must sync to a secure cloud back-end whenever the phone is online. • CSV/PDF export and Google Drive backup round the feature set so users can share reports at tax time or when applying for loans. Tech notes Android (Kotlin or Flutter are both fine). Please use a lightweight, well-documented architecture—MVVM with Room + Coroutines, or an equivalent if you prefer Flutter with Bloc/Provider. I’ll supply branding assets; you supply clean, commented code pushed to a private Git repo with regular commits I can review. Acceptance criteria – APK that installs and runs on Android 9+. – Source code meeting the documented architecture. – Unit tests for key view-model logic. – Short README covering build steps and third-party libraries. After this milestone I may expand to iOS and Web, so writing modular, portable code is a plus.
