You don't start at zero. You start at your edge.

These are the most common words in spoken Chinese, in the order you will meet them. tongtong learns where your knowledge thins out and teaches right there: never the words you already own, never the ones you can't reach yet.

Each tile is a real word. The blue band moves as you learn.45 known of 43,127

It already knows what to ask you next.

No lists to build and no level to guess. Open the app and the right card is waiting.

  1. One minute, one level

    Tap the words you recognise. A few dozen answers place you on a scale of 43,000 words, from first lesson to near-native.

  2. Always the right difficulty

    Each card sits where you still have to reach, but rarely miss. That is where memory grows fastest.

Past HSK 6. All the way to fluent.

Most courses stop where the textbook stops. tongtong keeps going: all nine HSK levels, then the thirty-two thousand words fluent speakers meet in films, the news and novels. Always the most useful first.

  • HSK 1–6, where most apps end5,400
  • HSK 7–9, the advanced levels5,600
  • Beyond HSK, by real-world frequency32,127

Stories that are almost easy.

The linguist Stephen Krashen called it i + 1: we learn best from language we mostly understand. tongtong picks stories built from the words you know, with just enough new ones to keep you reaching.

Questions, answered.

Is tongtong free?

Yes, to start, and the free plan is a real daily session: up to 60 cards in any 24 hours and one story a week, with the same algorithm as Plus. Plus removes both limits.

I'm a complete beginner. Is that fine?

Completely. The first minute works out what you already recognise, even if that is nothing, and starts from there. It works the same way if you're well past HSK 6.

Does it follow HSK 3.0?

Yes, all nine levels, plus thirty-two thousand more words beyond them, ranked by how often people actually use them.

Simplified or Traditional?

Either. Switch in Settings whenever you like; every word, sentence and story follows.

Which devices and languages?

The web, iPhone and Android, with one account and your progress in sync. The app speaks English, German, Spanish, French, Italian, Japanese, Korean, Portuguese and Russian.

How does it decide what I study?

Two models work together. One tracks your memory of every word you have met (spaced repetition, FSRS). The other keeps a running estimate of your level (item response theory). Together they pick the card that helps you most right now.

Your next review is due.
