About

LetterSprig

Features
Read full description

Beautiful handwriting takes a few minutes a day. LetterSprig is a short daily practice for writing by hand, on real paper, with your own pen. Learn to write a new script like Japanese hiragana, Arabic, Korean Hangul, Russian cursive or Hindi Devanagari, or make your everyday handwriting neater in your own language. HOW IT WORKS • Pick one of 30 languages. Where it applies, choose print or cursive. • Each mission takes 5, 7 or 10 minutes: study the model, see the stroke order where it exists, write on paper, then check your page. • Spaced review brings back the letters you are about to forget, a few at a time. • Letter check (beta): photograph your page and see which letters read clearly and which look like a different letter. It does not grade style yet, and it is not available for Chinese yet. If the photo is not clear enough, no check is used. 30 LANGUAGES, 12 SCRIPTS Portuguese, English, Spanish, French, German, Italian, Dutch, Swedish, Norwegian, Danish, Finnish, Polish, Czech, Romanian, Turkish, Vietnamese, Indonesian, Japanese (hiragana), Chinese (simplified and traditional), Korean, Arabic, Hebrew, Hindi, Bangla, Urdu, Tamil, Thai, Russian, Ukrainian and Greek. The app speaks 31 interface languages, and the language you practice is independent of the app's language. MADE FOR ADULTS No hearts that block you, no guilt notifications, no leaderboards. Your streak counts the weeks you met your own goal, and missing a day never erases what you learned. PRINTABLE SHEETS A4 and US Letter practice sheets with the right guides for each script: four lines for Latin letters, squares for Chinese and Japanese, a headline for Hindi and Bangla. PRIVATE BY DESIGN No account needed. No ads, no tracking. Your progress stays on your device. A photo leaves your phone only when you ask for a letter check, and it is deleted from our server within 24 hours. LETTERSPRIG PLUS The first three missions of every course are free, with 3 letter checks. Plus Lifetime is a one-time purchase that unlocks all 30 missions of all 30 courses and printable sheets for every mission, forever, and includes 100 letter checks. Plus is also available as an annual plan (with a 7-day free trial) or a monthly plan, both with 150 letter checks a month. More letter checks come in packs that never expire. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings. Terms of Use: https://lettersprig.runu.com.br/legal/terms Privacy Policy: https://lettersprig.runu.com.br/legal/privacy
