Build an Investment Portfolio Tracker App

Develop a mobile app that empowers users to track their investments in stocks, crypto, mutual funds, and more—offering real-time data, asset allocation charts, and financial insights.

Why Build an Investment Tracker App?

As personal investing becomes more mainstream, users need powerful tools to monitor their portfolios across various asset classes. Building this app teaches you data visualization, API integration, financial modeling, and mobile-friendly dashboard design—making it a comprehensive app development project.

Users can connect external brokers, manually input assets, and visualize their portfolio’s total value, gain/loss, asset distribution, and performance trends. Support syncing with stock, crypto, and fund APIs.

Key Features to Implement

Add stocks, crypto, or funds manually or via integrated brokerage APIs.
Live price updates fetch asset values and update performance dashboards.
Charts show historical value, asset allocation, and returns by category.
