Drops does not currently offer a Breton course; included as a reference for what generic vocab-only apps cover. Skol Ober is a correspondence course with real human tutor feedback, which an app cannot replace. Memrise has community-built Breton decks. blas. is the only mobile app that drills the mutation system for Breton and ships graded reading. Last verified May 2026.

Why Breton needs more than a vocab app

Brezhoneg has four mutations, complex initial consonant changes, and dialect variation. Generic apps skip all of it.

Four mutations

Soft, spirant, hard, and mixed mutations drilled with the triggers that produce them.

Kemmadurioù in context

Mutation practice tied to real sentences and verbs, not isolated tables to memorise.

Sourced Brezhoneg

Breton text is sourced or curated, never AI-generated. The Brezhoneg you see is real Brezhoneg.

No Duolingo Breton

Duolingo never built a Breton course. blas. fills the gap with a curriculum from absolute beginner upward.
