📝 About this app

With this app you can transliterate text to runes based on a phonetic correspondence with Latin or Cyrillic letters. This app translates the sounds of words, not the meaning. It is a good source for rune pronunciation and learning about the runic alphabets.

Supports the following major runic families:

• Elder Futhark runes (Common Germanic Fuþark)
• Swedish-Norwegian Fuþąrk (Rök; Younger Futhark, short twig)
• Danish Fuþąrk (Younger Futhark, long branch)
• Medieval rune alphabets
• The runes that J. R. R. Tolkien invented for Cirth (the rune script from The Hobbit / Lord of the Rings)

Supports Ogham (Old Irish script):
• Aicme Beithe / hÚatha / Muine / Ailme
• Forfeda (the letters added later)

For premium users:
• Anglo-Saxon runes (Anglo-Frisian Fuþorc)
• Old Turkic (Göktürk script / Orkhon script / Orkhon-Yenisey)
• Old Hungarian runes (rovásírás)
• Armanen runes (Armanen Futharkh)
• Gothic
• Old Italic
• Glagolitic (Old Slavonic "Glagolitsa", sometimes known as Slavic runes)
• Phoenician

Text is transcribed to runes based on a phonetic representation (English, Russian or language agnostic).
