Practice Chinese writing with Skritter, whether you have a strong grasp of written Chinese and want to remember the characters better or are a beginner who doesn’t know where to start. Skritter has existed for more than 10 years, and for a good reason: our learners are amazing! They help us with feedback which allows us to create what we think is the best Chinese writing app out there! If you have seen Chinese writing before, you probably noticed that it requires us to learn characters rather than the roman alphabet we know from English. You can learn it through our “decks” (similar to a card deck) based on topics and difficulty. Popular Decks: - Ordering or making coffee or tea (so you can get your morning caffeine fix) - Chinese Stroke Order - HSK 1-6 & New HSK3.0 1-9 study decks - More advanced topics like Yoga and talking about your Emotions - The 16-episode Ultimate Chinese Character course First, you learn a character’s meaning, reading, and tone; then practice writing it! Before you know it, you’ll want to learn thousands of characters, and words like these two happy users: “If I could only keep one app on my iPod, this would be it without a doubt. Skritter will change your life!” ― Wendy Werneth, UN Translator “Learning to write characters has never been so fun. From writing zero to 2000+ characters in six months!” ― Brian Jackson, Economist Try our app and see for yourself why thousands of people use it every day. Have questions, problems, or feedback? We would love to hear from you. Reach out to us at team@skritter.com ----------- Guest accounts enjoy free access to select decks forever!

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.
