Echo Fluent turns podcasts you already love into a spoken-English workout. Pick any podcast, and Echo Fluent breaks each episode into short, manageable chunks. For every chunk you: 1. Listen to the native speaker 2. Read along with the transcript 3. Record yourself repeating it 4. Compare your recording to the original This "shadowing" technique — used by language coaches worldwide — trains your ear, mouth, and rhythm together, helping you sound more natural rather than just knowing more vocabulary. FEATURES • Subscribe to any podcast and practice with real, unscripted English • Automatic chunking breaks episodes into bite-sized practice segments • Built-in transcript and recording playback for instant comparison • Daily streak tracking keeps you consistent • Everything syncs automatically via iCloud across your devices • Free daily practice allowance, with Echo Fluent Premium for unlimited practice Whether you're preparing for an interview, want to reduce your accent, or just want to sound more confident speaking English, Echo Fluent gives you a simple daily habit built around content you actually want to listen to.
