The entire dictionary lives on your device. No internet connection required — ever.
Your Dictionary, Everywhere
All 160,000+ entries in the duiduidui! dictionary are stored locally on your device. That means you can look up any character, word, phrase, or sentence without needing Wi-Fi or cellular data. On the subway in Beijing, on a flight to Shanghai, in a rural village with no signal — your entire Chinese dictionary is always available.
Offline Study Sessions
Flashcard reviews work without an internet connection, too. The adaptive study system runs entirely on your device, so you can study anywhere — on your morning commute, during a lunch break, or in a cafe without Wi-Fi. Your progress syncs when you reconnect, but you never have to wait for a connection to start learning.
Offline Search
The app's full search capabilities work offline. Search by Chinese characters, pinyin, or English. Apply filters by tags, difficulty, or mastery level. Everything runs locally, so searches are fast and always available — even when you need them most, like trying to read a menu or understand a sign in a place where you can't get online.
