Recommendation. Promising but needs more demand evidence before committing.

Why market gap = high

There are few dedicated offline vocabulary apps that effectively integrate spaced repetition without requiring subscriptions, indicating a market gap.

Why feasibility = high

A small team could develop a focused offline app with basic spaced repetition features within a few months.

Market gap and feasibility are LLM-estimated and directional — not market research. Treat as starting points for your own validation.
