Vanifer is a beautifully simple Spanish flashcard app, designed for adult learners who want their study time to feel modern, focused, and a little bit fun. STUDY Tap a card to flip it. Swipe to the next one. That's the whole gesture vocabulary. Filter by vocabulary, verbs, conjugation, grammar, or phrases — alone or in combination — to drill exactly what you're working on. ADD YOUR OWN Cards are yours. Build out your deck as you go, with optional notes for the things that always trip you up (gender, irregular conjugations, ser-vs-estar subtleties). QUIZ YOURSELF Pick categories, pick how many cards from each, and Vanifer assembles a quiz on the spot. Flip to reveal the answer, mark yourself correct or incorrect, and finish with a clean score breakdown by category. DESIGNED FOR THE NEW iOS Vanifer is built natively in SwiftUI and embraces the Liquid Glass design language — translucent surfaces, a slow aurora background, and physics that feel right under your thumb. It looks beautiful on every device, light or dark. NO ACCOUNT, NO ADS, NO TRACKING There is no sign-in. There is no advertising. There is no analytics. Your deck lives on your device. The only network call the app ever makes is a public read to fetch the latest community-curated deck — never your data going out.
