Why it works

Language apps retain via streaks and spaced repetition; a focused pair beats trying to be Duolingo.

Who it's for

Learners of a specific language (English for X-speakers, French, Spanish).

How to build it
1. Build a lesson engine with spaced repetition + streaks. 2. Seed 30–50 lessons for one pair. 3. Freemium: free basics, paid full path + speaking practice.
