## What is Recursio?

Recursio helps English learners stop forgetting the words, phrases, and grammar they already study.

Build your own vocabulary, practice what matters to you, and let Recursio bring weak spots back into review. Instead of following a fixed course path, you choose what to learn: useful words, everyday phrases, grammar topics, sentence practice, speaking practice, and focused Coach sessions.

NEW: Phrases
Recursio now teaches phrases, not just single words. Save phrasal verbs, collocations, idioms, and everyday conversational chunks like "look forward to," "make a decision," or "to be honest." Phrases live in the same vocabulary space as your words — just switch between the Words and Phrases filters. They practice through the same exercises and return in your daily Mixed Review, so the phrases you save today come back at the right time tomorrow.

Recursio is designed for learners who can already work in English at a basic level. Definitions, examples, grammar explanations, and practice prompts are shown in English, so you stay inside real English instead of constantly 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, goal, or context. Pro users can create multiple private spaces, such as Work, Travel, Exams, Movies, or 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.
- 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.
- Coach
Practice thematic chats and focused language-learning drills. Coach stays focused on English practice and can help route weak grammar and vocabulary 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.

Free plan includes core vocabulary tools for words and phrases, one vocabulary space, built-in practice, basic dictation voice, and grammar topic practice.
SMART unlocks premium AI practice, Coach access, 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, and grammar that still need work.

## Version history (last 5 releases)

### 1.4.3 — 2026-08-27

Stability and performance improvements throughout the app, plus a refreshed sign-in screen. Thanks for learning with Recursio.

### 1.4.2 — 2026-08-23

This update is all about Speaking Practice.

• Recording no longer stays stuck listening — it ends on its own once you finish speaking, and tells you if nothing was heard.
• If a call, another app or the camera takes the microphone, the exercise says so and lets you try again, instead of quietly doing nothing.
• Much lower CPU use during Speaking Practice, so your device runs cooler and the battery lasts longer.
• Various fixes and stability improvements.

### 1.3 — 2026-07-11

New: Phrases
Recursio now teaches phrases, not just single words. Save phrasal verbs, collocations, idioms, and everyday conversational chunks, then practice them in the same exercises as your words — dictation, sentence building, speaking, and writing. Saved phrases join your daily Mixed Review and come back when you need them.

You can also open a phrase straight from a Recursio video or lesson link and save it to practice in one tap.

Also in this update:
- Words and Phrases filters in your vocabulary list
- Practice and Mixed Review improvements
- Sentence Builder and speaking recognition refinements
- iPad interface improvements
- Various fixes and stability improvements
