Reach A2 in a New Language

5 milestones · 16 weeks

A2 is the level where a learner moves from survival phrases to handling familiar, everyday topics with some independence: routines, family, work, shopping, simple plans. This is the level most language apps claim to deliver but rarely do, because app-based learning optimizes for streak retention, not real conversational ability. Every milestone requires proof of real human communication — a recorded conversation with a native speaker. App scores are not accepted at any level.

Reach B1 in a New Language

5 milestones · 20 weeks

B1 is the intermediate plateau — where many learners stall for months or years. Moving from A2 (familiar topics, past and future tense, 20-minute conversation) to B1 requires a genuine expansion into sustained narrative, defended opinions, hypothetical language, and improvised problem-solving. Every milestone requires a real recorded conversation with a native speaker. App scores are not accepted at any level.
