Account and billing

Web, iOS and Android

The website, iOS and Android use one account, with a shared dictionary and saved learning progress. Core practice is available in all clients. Sections and some actions differ between platforms, and new features sometimes require an app update.

Available in every app

  • Your dictionary and daily sessions with reviews.
  • Grammar and radicals.
  • Handwriting practice and phrase drills.
  • Dialogues, situations and reading: texts, news, the daily text.
  • Settings, subscription and support.

Web only

  • The journal — writing in Chinese with familiar words highlighted.
  • The idioms section inside your account.

None of this affects the learning itself: your dictionary, review schedule and progress are the same wherever you study from.

Where to download the apps

The web version runs in a browser and needs no installation. Sign-in is the same everywhere — the account is shared.

Which device suits what

Handwriting is noticeably better on a phone or tablet — a finger or stylus is closer to real writing than a mouse. Long reading and working through texts, on the other hand, are easier on a large screen.

What stays on a device

An unfinished Dui-dui board stays on the device, so sharing an account does not move a started round to another phone. The recent words widget also reads a local set that the app refreshes separately.

Chrome extension

This is a separate client for reading other websites. Once connected, it adds words to your shared dictionary, but does not sync its local list and sources between devices. It is currently in a pilot, installed from a folder and not yet published in the Chrome Web Store.

What to do if…

I studied on my phone but the web shows old progress

Reload the page: the web pulls state on load. If the mismatch persists, check that you are signed into the same account in both places.

I cannot find a section in the app that I saw on the web

The journal and idioms are currently web-only. For other features, check your app version and the Practice and Materials tabs. What's new also lists the platforms for each feature.
