Why Celtic languages need their own app
All six Celtic languages share features that generic language apps struggle with: initial consonant mutations, verb-first word order, the copula, dialect variation, and noun declension. Generic apps either skip these features or get them wrong.
blas. was built around them. Mutation drilling, dialect-aware audio, structured grammar, and spaced repetition that adapts to your weak spots.
