Echo Loop

Echo Loop is an English learning app that guides users through a structured listen-to-speak cycle: blind listening, sentence drilling, shadowing with AI pronunciation scoring, and paragraph retelling. The app automates the entire training process, scheduling review tasks over 28 days with spaced repetition, so learners focus only on practice rather than planning. It features thought-group transcription for clarity, AI-powered translation and grammar analysis, and tracks progress across listening time, output ratios, and vocabulary growth.

Designed for learners who want to deeply practice audio material rather than constantly consume new content, Echo Loop combines multiple proven techniques into one continuous loop. The app is available on iOS, Android, Windows, and macOS. According to the project's documentation, it was built using Claude AI tools.
