981 vocabulary words, smart spaced repetition, quizzes in both directions, and a streak tracker — all offline, no account needed.
Tap to flip between Spanish and English. Mark each word as "Got it" or "Keep practising". The app automatically brings back the words you find hardest.
Three modes: Spanish → English, English → Spanish, and Mixed. Four options per card with instant colour feedback and automatic scoring at the end.
Tap the speaker on any card to hear the Spanish word pronounced at natural speed. Powered by iOS text-to-speech — works even with the mute switch on.
Sessions are capped at 20 words and built from four priority buckets: unseen first, then weak words, medium, and finally strong — so study time is never wasted.
A daily flame streak keeps motivation high. The Progress tab shows current streak, longest streak, total sessions, and a mastery bar for every unit.
Work through IB-style sentences about daily routine. Tap to reveal the English translation and listen to the full sentence at exam pace.
Choose any of the 21 units from Diverso Nuevo Básico — from Unidad 0 Hola all the way to Unidad 18 Tecnología. Each unit shows how many words you've mastered and your current progress bar.
Start with flashcards to learn new words, then challenge yourself with a multiple choice quiz in Spanish → English, English → Spanish, or Mixed direction. Each session is 20 words, prioritised by what you need most.
Every answer updates your mastery score in real time. Come back the next day — your streak grows, weak words are automatically queued first, and you can see at a glance exactly which units need more work.
