Details
Dialogue-plus-explanation lessons with transcripts, line-by-line breakdowns and flashcards, covering absolute beginner through lower intermediate. The sheer volume makes it a decent daily listening habit, and a free account gives real access before you commit. Two caveats: the catalogue mixes varieties without always making the distinction obvious, so check whether a lesson is formal Arabic or dialect; and the marketing is relentless, with prices only reasonable during their frequent sales.
