HCB Mobile

What is HCB Mobile?

HCB Mobile is a React Native application built with Expo that enables nonprofit organizations to manage their finances on the go. Developed by Hack Club, the app serves the HCB (Hack Club Bank) platform, which processes $6 million monthly for over 6,500 nonprofit organizations worldwide. The app allows users to issue cards, view transactions, and manage their HCB organizations directly from their mobile devices. It provides essential banking functionality tailored for nonprofits that rely on HCB's fiscal sponsorship services. Built by a full-time student developer, HCB Mobile successfully navigated Apple and Google's app store approval processes—a notable achievement given the complexity of launching financial applications on mobile platforms. The application is open source, allowing community contributions and transparency in its development. The project demonstrates practical implementation of React Native for fintech applications serving a specific organizational need. Users can access core financial management features without requiring desktop access, improving accessibility for nonprofit teams managing multiple locations or working remotely. HCB Mobile is available on both iOS and Android platforms through their respective app stores, with the source code available on GitHub for developers interested in the technical implementation or contributing to the project.
