## What it is
Echo Loop is an open-source Flutter-based English listening and speaking training app that guides learners through a structured listen-to-speak cycle: blind listening, sentence-by-sentence intensive listening, shadowing with real-time AI pronunciation scoring, and paragraph retelling. It automatically schedules an 8-stage, 28-day spaced-repetition review cycle with reminders, so learners can build listening and speaking skills without designing their own study plan.

## Use cases
- practice english listening comprehension with real audio
- improve my english speaking through shadowing exercises
- learn english with spaced repetition and automatic review reminders
- get ai feedback on my english pronunciation
- train myself to understand english without subtitles
- turn listening practice into actual speaking ability
- english listening and speaking training app with daily streak tracking

## When to choose
- You want a structured, science-backed listen-to-speak training loop instead of passively consuming English podcasts or videos
- You need automatic spaced-repetition scheduling and reminders to build a consistent daily study habit
- You want real-time AI pronunciation scoring while shadowing bookmarked sentences
- You prefer an open-source alternative to commercial language-learning apps

## When to avoid
- You need grammar-focused or written-exam English preparation rather than listening and speaking practice
- You want to learn languages other than English
- You prefer casual content browsing over a demanding, structured daily drilling routine
