KoKo teaches the vocabulary of a language, and only that. Over 6,000 ready-made words in 38 everyday topics, in 30+ languages: no cards to build, unlike Anki. Each word is learned in 4 short steps, then reviewed 6 times, from the next day to 4 months later. Sessions take a few minutes, never more than 32 reviews a day. Widgets, streaks, mini-games, offline, no account, no ads. iPhone only. Free with one topic open, the rest with a subscription.

Partial The app shell, spaced-repetition scheduling, and review flow are standard and vibe-codeable. The hard part is the curated content: 6,000+ words in 38 topics across 30+ languages, which needs real linguistic data and quality review.
What it would actually take: The app itself is a standard SRS app: a web or mobile client, a backend for progress, and a scheduler based on SM-2 or FSRS. The hard part is building a high-quality, licensed, multilingual word list with translations, audio, and example sentences. That takes lexicographers or native-speaker reviewers and rights to the content, plus an ongoing curation pipeline.
