Speaking practice whenever you have a minute, for learners past the basics who know more than they can comfortably say. You may understand the language when you read or listen, but still struggle to find your words in a conversation. Bubblz gives you a private place to use the language you already know before the moment feels high-stakes. Choose a situation, speak or type, get feedback, and try again. This is not another lesson to complete. Bubblz is conversation practice for turning knowledge into something you can actually use. With Bubblz, you can: - Practice real conversations for daily life, work, travel, dating, family, and the situations you want to feel ready for - Speak or type whenever you have time, without coordinating with a tutor or language partner - Get corrections while you practice, so you can catch mistakes and try more natural phrasing - Repeat tricky situations until your next answer comes more easily - Choose guided topics or create a conversation around your own life Bubblz is built for post-beginner through advanced learners, from A2 to C1. Conversations and feedback adapt to your level, so you are not pushed back into beginner lessons when you are ready to use more of the language. Practice English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, and Korean. Spanish, Portuguese, and English include regional options. Bubblz is not a course for learning a language from scratch. If you are a complete beginner, start with the foundations first. Bubblz is for the point where you know some of the language and need more chances to use it. Try Bubblz free and practice the conversations that matter to you.

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. Plans are available on a monthly or annual basis. Your payment is charged to your iTunes account. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period. You can turn off auto-renewal at any time by going to your Account Settings on the App Store after purchase. Start your journey with a 14-day free trial on annual plans—cancel anytime to avoid charges. You will always have permanent access to notes created during the trial period or while your subscription was active. However, an active subscription is required to create new notes or edit existing ones in languages other than the first target language you added in Duory. Notes created in the first target language you add to Duory remain editable forever with or without an active subscription. LANGUAGE TRANSLATION SUPPORT ** Duory uses Apple’s Translation API for on-device translation. Here’s the full list of supported languages: • Arabic • Chinese (Mandarin, Simplified) • Chinese (Mandarin, Traditional) • Dutch • English • French • German • Hindi • Indonesian • Italian • Japanese • Korean • Polish • Portuguese (Brazil) • Russian • Spanish (Spain) • Thai • Turkish • Ukrainian • Vietnamese PRIVACY Duory is designed with your privacy in mind.
