Recursio helps English and Spanish learners stop forgetting the words, phrases, verbs, and grammar they already study. Build your own vocabulary, practice what matters to you, and let Recursio bring weak spots back into review. You choose what to learn: words, phrases, verbs, grammar, sentences, speaking, Coach sessions. Or let Daily Five choose for you. NEW: Daily Five One short routine every day: review a few of your words, three verb tasks, and one sentence. Keep your streak, with one free skip a week. Five minutes is enough. NEW: Verb Trainer Practice verbs in every tense and mood, always inside a complete sentence: 338 English verbs across 7 tenses, 356 Spanish verbs across 8 tenses. Learn in the language you learn Choose English or Spanish as your learning language. Spanish comes with a 3,400-word dictionary with simple Spanish definitions, 100 grammar topics from A1 to B2, 300 everyday phrases, and a Coach that talks to you in Spanish, including real-life scenes like ordering at a restaurant. The app interface is available in English and Spanish. Recursio is for learners who already have a basic level. Definitions, examples, explanations, and prompts are shown in the language you learn, so you stay inside it instead of translating. Main features: • Personal vocabulary Add words and phrases you want to remember, including ones outside the built-in dictionary. • Phrases Save phrasal verbs, collocations, idioms, and conversational chunks, and practice them alongside your words. • Vocabulary Spaces Organize words and phrases by topic or goal. Pro users can create multiple spaces: Work, Travel, Exams, My mistakes. • Word & Phrase Practice Review active items through dictation, sentence building, speaking transcript practice, writing scaffold, and mixed review. • Premium Cloud Voices Pro users can hear premium cloud-generated voices for Dictation and Speaking Practice. • Grammar topics Study structured grammar topics with short explanations, examples, common mistakes, and built-in practice. Spanish now covers A1 to B2. • AI Grammar Practice one grammar topic more deeply with fresh guided exercises and short explanations. • Sentence Check Write sentences with target words or phrases and get feedback on clarity, grammar, naturalness, and task fit. • AI Speaking Practice Read aloud, compare what the app recognized with the target sentence, and practice focused phrase drills based on your result. Forgiving by default; choose a stricter mode in Settings. • Coach Thematic chats and focused drills in the language you learn; weak grammar and vocabulary go back into review. • Progress insights Pro users can see weak items, practice rhythm, recall load, and recommended next steps. • Adaptive recall Recursio tracks confidence, mistakes, and resurfacing signals so important weak spots return at the right time. • iPhone and iPad A layout made for both, in portrait and landscape. Free plan includes core vocabulary tools for words and phrases, one vocabulary space, built-in practice, Daily Five, Verb Trainer, basic dictation voice, and grammar topic practice. SMART unlocks premium AI practice, Coach access, a Coach mini-chat inside Daily Five, expanded capacity, and deeper guided practice for vocabulary, grammar, and writing. PRO unlocks Premium Cloud Voices, AI Speaking Practice, Progress insights, Vocabulary Spaces, higher daily AI limits, and the full premium learning layer. Recursio is not a flashcard deck, not a fixed beginner course, and not a generic chatbot. It is a focused language practice system for remembering more, writing better, and returning to the words, phrases, verbs, and grammar that still need work.
