Save time and stay focused—no more bouncing between translation apps, Google search and your notes. Study, practice, and reflect with dynamic language notes. Why Duory? • Duory is the smartest way to take language notes on your phone. • Duory lets you keep and organize notes for all your target languages in one place. • Save time and stay focused — no more bouncing between Google Search and your notes. • Practice hands-free while doing boring chores. • Improve your output by journaling in your target languages. • Capture interesting phrases from anywhere! • Browse vocabulary from your own notes in a focused, immersive way. • Make them stick with Home and Lock Screen widgets. • Duory supports 40 target languages. NOTES • Duory is designed to perform language tasks on-device thanks to Apple’s language APIs and other offline language tools. • To perform translations, iOS needs to download language dictionaries for each language pair. This only happens once for each pair. • Duory requires access to your microphone for you to record pronunciation of phrases and your camera for scanning text. FREE FOREVER Get started for free with these features: • Create notes and journals in one target language. • Enhance your language journals with Apple Journaling Suggestions. • Capture phrases from your physical textbooks, Duolingo sessions, images, or RTF/PDF documents. • Use a handy widget to reinforce recently learned words and phrases. • In-app translation and transliteration, including Hiragana and Pinyin. • Record and play back your phrases (no playlists on the free plan). • Access notes you create during your free trial or subscription – forever! Important: If you create notes in target languages outside of the initial language during an active subscription, they will become read-only when your subscription expires (the notes you create in your oldest target language will remain editable forever) DUORY PLUS PLANS Unlock the full power of Duory with a subscription: • Create notes and journals in multiple languages. • Turn your phrases into playlists for hands-free practice. • Control playback from your lock screen or Control Center. • Turn plain notes into memorable ones with stickers and pictures. • Sync your notes and journals to iCloud.
