Project Summary

Five rebuilt Rosetta Stone’s mobile apps from a cross-compiled architecture into native iOS and Android applications, delivering frontend design, backend development, and usability testing. The relaunch led to doubled app-store users and revenue, high review scores, and the project was delivered ahead of schedule and below budget.

Key Challenges

Replace a cross-compiled app with native iOS and Android builds
Ensure a careful rollout to avoid disruptions in school systems that use the app

Project Deliverables

Project Solution

Five rebuilt Rosetta Stone’s cross-compiled mobile apps as native iOS and Android applications and implemented the backend services. The vendor led UX workshops, concept work and usability testing before building, and supplied a core team of approximately six people including designers, a project manager, and multiple backend developers. The process included iterative build-and-test cycles, careful rollout planning to avoid education-system disruptions, and close coordination with the client.

Project Outcome

Deliverables were completed ahead of schedule and below budget
Signup rates and the user base approximately doubled after launch
App-store revenue roughly doubled compared to the previous app
High customer ratings (around 4.6–4.7 stars) and the product paid for itself
