The official Beta has a lot of content to represent the final version of the app. Languages are being updated regularly and Spanish and French will be the first to be available in full in the Beta, most likely before December already.
The later final release will have way, way more content for all languages as promised in the campaign, including our full pronunciation trainers (all 500-900 cards of them), our 625 word list, our custom frequency list, and the ability to add whatever custom content you want.
