Heidi is a calm, beautiful way to build real German vocabulary — 3,092 carefully chosen words, each on a quiet card with its article, an English meaning, a natural example and warm native audio. You practise with gentle spaced review that brings words back just before you'd forget them. Beyond the cards, a growing library helps it click: der / die / das gender guides, grammar cheat sheets, email and letter templates, exam prep and printable study sheets.
Heidi takes you from your very first words right up to B1 — the “independent user” level on the European framework (CEFR), and the level Germany asks for permanent residency and citizenship. The 3,092 words are the practical core of everyday German, so complete beginners grow into the list while intermediate learners use it to fill the gaps.
