The solo dev playbook: ship faster with Expo, EAS Build, and OTA Updates

Liam Du, founder of Wellspoken, developed an app to help improve real-time articulation during everyday conversations after experiencing personal challenges in effectively communicating his ideas. The app offers personalized practice sessions, daily exercises, and AI-powered speech analysis to help users organize and express their thoughts more clearly. Built using Expo, a framework that simplifies mobile app development, Wellspoken was rapidly developed and shipped within a week, thanks to Expo's features like audio recording, camera functionality, push notifications, and secure storage, all handled through clean TypeScript APIs without native coding. The app's fast iteration and deployment capabilities, including over-the-air updates, allowed for quick bug fixes and enhancements without app store delays. Since its launch, Wellspoken has gained over 400 users and generated $500 in revenue, highlighting the demand for tools that aid in effective communication.
