Let’s build ‘Ghar Ka Kharch’, a family-first expense and bill-reminder app for households in India’s tier-2 to tier-4 cities. Families should be able to quickly log shared spends by familiar categories (groceries, daily milk, gas cylinder refills, school fees, etc.), see monthly/weekly summaries with simple bar or pie charts, and set up recurring reminders so due dates aren’t missed. Everything works offline with all data kept on the device in an encrypted database, and the app should feel smooth on entry-level phones (2 GB RAM) as well as higher-end devices.

Implementation notes:
- Kotlin + Jetpack Compose for a friendly, accessible UI
- Local notifications for recurring bills (no backend)
- Encrypted Room for storage
- Target SDK 35, min SDK 28
- First-class Hindi (hi-IN) and English
- Works with gesture and 3-button navigation across all screen densities
- Dev and release build flavors so development logs are stripped from production
