Delivery story

Palingo: English Vocabulary: a focused product delivered from discovery to release

01

Challenge

The client needed a focused product for English vocabulary learners. The first release needed adaptive word practice, AI explanations, and retention reviews, while managing content growth and learner drop-off.

02

How we built it

We mapped the core journey and data model first, then delivered adaptive word practice as a working vertical slice. The next iteration added AI explanations and retention reviews, with authentication, validation, loading and failure states designed into each flow. A mobile-first TypeScript build using React Native, Expo, TypeScript, Supabase kept the interface and service contracts consistent; the final weeks focused on QA, accessibility, and release preparation.

03

Delivery

The delivered 8-week MVP let English vocabulary learners complete the core journey without relying on disconnected tools. It provided a small, maintainable foundation for testing demand and prioritising the next release.

Coralsoft turned the product brief into a maintainable 8-week MVP.
