ttdictionary is a family of 104 offline dictionary apps for Android and iOS, developed since 2014. It covers 30 languages with bilingual dictionaries for 49 language pairs, monolingual explanatory dictionaries and themed dictionaries. All apps share one engine: offline search, an optional AI assistant, text-to-speech, flashcards, quizzes and a word game.

The dictionaries cover 30 languages, from English, German, French, Spanish, Italian, Turkish and Russian to Azerbaijani, Kazakh, Uzbek, Ukrainian, Polish, Arabic, Persian, Japanese and Chinese. The full list with app counts is on the apps page; every language has its own hub page. The app interface itself is available in 9 languages.

There are bilingual dictionaries for 49 language pairs, for example English–German, English–Spanish, English–French, English–Turkish, Russian–English, Russian–German, German–Turkish and Kazakh–Chinese. Every bilingual app translates in both directions and can search both languages at once. The complete list is in the language pairs section of the home page.

Yes. On Android each dictionary is a separate free app on Google Play (104 apps). On iPhone and iPad there is one App Store app, TTdictionary, which contains 93 downloadable dictionaries; install it once and download the dictionaries you need inside the app. There is no web or desktop version.

Yes. Every ttdictionary app is free to download and use, supported by ads. The optional Pro subscription removes all ads, lifts feature limits (for example the number of bookmarks and training sets) and gives a much higher quota of AI requests.

Yes. The dictionary database is stored on your device, so search, word cards, favorites, flashcards, quizzes and the listening player all work offline. Internet is needed only for AI commands, online backup and downloading additional dictionaries.

Yes, through text-to-speech: every word and its description can be read aloud, each language with its own voice, and a background player reads whole word lists at 0.5×, 1× or 2× speed. The AI assistant can also write a pronunciation guide for a word. The dictionaries do not contain recorded human audio.

Yes. Every app has flashcards, a multiple-choice quiz, a listening test and a daily word game. Training sets are built from your favorites, bookmarks, history or a random selection; after a session you can repeat only the words you missed. On Android a home-screen widget runs a flashcard session without opening the app.

Each dictionary database ships inside the app and is updated together with app releases on Google Play and the App Store; the release notes for every version are listed on the app pages of this site. Between releases you can correct entries and add your own words in the app, and the AI assistant can find words the database does not have.

Install the TTdictionary app from the App Store, open the dictionary list, download the dictionary you need and activate it. On iOS all dictionaries live inside that one app; the site's app pages show an App Store badge when a dictionary is available there.

Open Apps and tap a language chip, or go straight to a language page such as /apps/language/italian/. You can also filter by type: bilingual, monolingual, themed.

Yes. Tap + on the search tab, type the word and its definition, or let the AI write the definition. Bulk mode adds many words from a list. Added words show a profile marker and can be used in flashcards and quizzes.

You can add your personal lists next to the dictionary: favorites, bookmarks, added words, edited words, known words and unknown words. Activate a list to search only inside it, then long-press to select several words and favorite, bookmark, listen to, export, delete or train them at once.

In the word card, tap the AI button and pick a command: explanation with context, synonyms, pronunciation guide, or find a word missing from the dictionary. Free users have per-minute, hourly and daily limits, and a short ad can earn extra requests. Pro users get a much higher quota.

Use Backup in Settings: online backup with a Google sign-in, a local file, or Dropbox. On the new phone sign in or pick the file and restore. Favorites, bookmarks, notes, history, added and edited words and settings are all included.

In bilingual dictionaries use the direction switch in the toolbar: first language → second, second → first, or both at once. Voice search and text-to-speech follow the chosen direction.
