Phabetia
Learn the alphabet until you stop thinking about the alphabet.
Open Phabetia (opens on the project's site)
Phabetia is a minimalist progressive web app (PWA) for learning to recognise and read the characters of other writing systems through repetition, progressive practice and light gamification. Learn to actually read another alphabet, not to transliterate it.
Greek, Cyrillic (Russian, Ukrainian, Bulgarian and Serbian), Runic, Georgian, Armenian and Arabic alphabets. Sessions under a minute, smart repetition, level-based progression with reviews, and it works offline with no account. Optional account to sync progress and compete in rankings.
