Android Expense & Family Budget Tracker (MVP)

Family Expense Monitoring & Budget Management App (MVP)
Project Overview

I am looking for an experienced mobile app developer or full-stack development team to build an MVP of a Family Expense Monitoring and Budget Management application.

The application will automatically track expenses from financial SMS messages on Android devices and provide spending insights, budget management, and family expense visibility.

The system should support family groups where members voluntarily join and share their spending data with authorized family members.

Objective

Most people do not know where their money is going each month.

The goal of this application is to:

Automatically track expenses from SMS notifications.
Categorize spending.
Generate spending insights.
Allow family members to share expense data within a family group.
Help parents manage allowances and budgets for children.
Help couples and families monitor household finances together.
