Flexi: Language Flashcards

Flexi builds your language flashcards for you.

Flexi: Language Flashcards is an AI flashcard maker and language learning app for iOS that generates cards with AI and schedules reviews using spaced repetition, so words come back just before you would forget them.

The app is free to download and use at a basic level.

Text-to-speech and home screen widgets are included without paying, which covers pronunciation practice and quick reviews.

Fields on each card are customizable, so you can decide what information a card holds, such as a translation, an example or a note.

Premium is where the extras sit.

Image generation for cards, word suggestions and flashcard import all require a subscription.

That matters if you already keep vocabulary lists elsewhere, because bringing them in is not part of the free tier.

Flexi is iOS only, so Android users will need to look elsewhere.

The app does not explain which spaced repetition algorithm it uses, which may bother learners who care about scheduling details.
