Discover the fascinating world of exotic alphabets and writing systems! Glyph is an app designed specifically for learning writing systems, not languages themselves. Want to learn to read and write Japanese hiragana, Korean hangul, Arabic script, the Georgian alphabet, or the vertical Manchu script? Glyph will help you master each character from scratch. Available writing systems: - Amharic (Ge'ez alphabet) - Japanese (hiragana, katakana) - Korean (Hangul) - Arabic - Inuktitut (Canadian syllabics) - Tamazight (Neo-Tifinagh) - Georgian (Mkhedruli alphabet) - Ukrainian (Cyrillic) - Greek - Manchu (the vertical script of the Qing dynasty) - More interesting scripts coming soon! Why Glyph? Unlike typical language apps, Glyph focuses exclusively on learning writing. You don't need to learn grammar or vocabulary—you focus on recognizing and writing characters. It's the perfect first step before learning a language! Glyph places a special emphasis on writing systems of less popular languages for which there is a lack of easily accessible and engaging educational materials. From the Canadian Inuktitut syllabics, through Berber Tifinagh, to the vertical Manchu script that once recorded the archives of an entire empire—you'll find courses here that practically no one else offers. Where no speech synthesizer exists (Tamazight, Manchu), the pronunciation was recorded by real human voices. Five types of exercises: - Drawing - draw characters with your finger and get instant feedback - From phonetics to characters - see the romanization and find the symbol - From characters to phonetics - recognize the character and match the pronunciation - Matching - pair characters with their sounds - Word writing - build real words character by character, top-to-bottom in vertical scripts! Smart learning: - The repetition system (SRS) ensures that knowledge is retained - Sections allow you to gradually master characters - Section guides and fun facts bring each script's history to life - Track your progress and unlock new levels Motivation: - Earn XP points - Maintain your daily streak - Track your progress in each section Glyph Pro: - Dark theme - Animation speed adjustment - More features coming soon! Offline mode: Learn anywhere without an internet connection. Download Glyph and discover that learning the alphabet can be fascinating!
