ADVANTAGES OF OUR APP: * Pronunciation by a native speaker * 2375 words split into 180 topic lessons * Does not require permanent Internet connection * Beautiful illustrations for each word * Phonetic transcription for each word * Dark interface to study at night * Choose from male and female voice * Built in app dictionary with progress * Game "True or False" to review pas material * Special lessons with favorite, difficult, old, random words * Flexible sound settings (music, speaker, effects) * Just 10-15 minutes per day to learn all words * For adults and teens 13+ Only 10-15 minutes per day - Spending just 10-15 minutes every day, will easily allow you to remember all useful Russian words. While memorizing words, the frequency of lesson is more important than duration of each lesson. 10 minutes on each day of the week will be more productive than one hour of tuition a week. One minute lessons - Taking into account busyness of modern life, we designed each lesson in the way so it would never take more than one minute to complete it! So you no longer need to search for free time to practice Russian! Simply, once you get a chance, launch the app and do one lesson at a time =) Short sessions will not affect efficiency of word memorization. Only useful Russian words - Russian for Beginners: LinDuo HD is a free and quick start to learn Russian language! Unlike others, we have only the most useful words, which are divided into 180 topic based lessons. Quality is here! Teach-yourself Russian is designed, that it will use your visual and echoic memory to help you memorize Russian words fast and easy! Special illustrations - We use only specially developed infographics (developed by psychologists), so your eyes can quickly identify meaning of word or action without stressing them with small unnecessary details. Word pronunciation by native speakers - Our app will help you master pronunciation of Russian words! Each word is recording by professional native speaker! Additionally, in the settings you can choose between male or female voice. Dynamic lesson difficulty - The app changes lesson difficulty gradually as you progress. To achieve this, it keeps stats for EVERY word! Example: in the spelling mode, initially you need to insert several missing letters in a word, then create a word having extra letters and finally, when you are ready, you will need to type the entire word on the keyboard. Modes for quick learning - The App includes four additional lesson types which are made of Favorites, Difficult, Old, Random words. You can add any word to your favorites and later create custom lesson from your Favorite words. Words are automatically added to "Difficult" (the ones you struggle to memorize) and "Old" sections. A "Random" mode will create a unique lesson. Do not need to know how to read - If you cannot read yet, no problem! Each word has a transcription in your language! And for more experienced ones, in the settings, you can choose a phonetic (like in a dictionary) transcription. Additional features - Thanks to your reviews, we are constantly updating the app to make it better! To help you take care of your eyesight, with just one tap, you can activate dark theme. If you temporarily do not have internet access, no problem! The App can work offline as well! Review Past Material - Many good apps do not pay enough attention to review past material! For this purpose we created the word game "True or False". It is very simple, but it's addictive and the most importantly, it helps to repeat past material and never to forget it! Support and Contact Us If you have any questions or suggestions, please never hesitate to send us an email admin@lin-duo.com - or use in-app contact form. We are always happy to answer your questions! Thank you very much for your trust and choice! If you like our app, do not forget to share it with your friends in social networks.

iSpeak is a voice-first AI tutor for the language you're trying to learn. You speak. Your AI tutor responds in real time. No menus, no flashcards, no pretending to "study" while scrolling. Just conversation. WHY ISPEAK IS DIFFERENT Most language apps test what you already know. iSpeak teaches you to speak the language you don't yet have. Every conversation is held at your level — A1 through C1 — and adapts as you grow. • Real conversations, not phrase drills • Your tutor gently corrects you in the moment without breaking the flow • Words you stumble on get saved automatically and surface again the next time you talk • Vocab review takes 4 minutes, not 40 • Pronunciation practice with native-speed audio • Daily streak that's about consistency, not guilt HOW IT WORKS 1. Pick a language and your starting level (A1 to C1) 2. Tap to start a conversation. Your tutor opens with a real question 3. Talk. Your tutor talks back. The transcript is saved with corrections 4. Review words you saved in 5-minute sessions 5. Track your weekly minutes, sessions, and the words you can now use LANGUAGES English, French, Spanish, Italian, German, Portuguese, Mandarin, and Russian. PRIVACY Your voice, transcript, selected language, level, and lesson context may be processed by iSpeak's AI providers, including Cloudflare Workers AI for transcription and DeepSeek for tutor replies. Transcript text stays with your account. We do not sell conversations or share them for advertising. The full privacy policy is at https://lilt-cu8.pages.dev/privacy. ISPEAK PREMIUM Premium is available as a monthly or annual auto-renewable subscription. It unlocks unlimited daily conversations, the full scenario library, pronunciation practice with native audio, detailed call corrections, and daily vocabulary review. Payment is charged to your Apple ID through the App Store. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can restore purchases from the paywall and manage or cancel your subscription from the Subscription screen. QUESTIONS? Email hello@lilt.app or visit https://lilt-cu8.pages.dev/help. We read every message. iSpeak — for the conversation you've been waiting to have.
