Real Estate Investment App for Small-Scale Investors

Project Overview

Our client, a real estate investment company, needed a comprehensive mobile application to serve small-scale investors who required better tools for managing their real estate portfolios. The app needed to provide real-time portfolio tracking, performance analytics, and fund management capabilities, all wrapped in an intuitive interface designed for non-technical users.

The Challenge

Portfolio Management Complexity

• Fragmented Information: Investors struggled to get a unified view of their portfolio performance across multiple properties and investments
