Case Study: Rosebud ships a native journaling app faster with Expo

Rosebud launches native app 30% faster with Expo

Rosebud, a therapist-backed journaling app, faced an existential challenge with less than a year of runway. Their customers' top request was for a native mobile app, but as a startup, they had no budget to hire separate iOS and Android specialists. The challenge was to build a native app without doubling engineering costs or requiring their small React team to learn entirely new languages.

Using Expo, Rosebud's three-person team built a native app for iOS and Android in just five months, which was 30% faster than a traditional native build would have been. The solution allowed them to reuse 70% of their business logic from their existing web codebase. As a result, Expo enabled Rosebud to launch its native app without splitting the team and reported 100% engineering retention post-launch.
