Record a phrase. Hear it backwards. Mimic that weird take, flip your attempt, and score how close you sound to the original. The reverse-voice party challenge—funny for game night, road trips, and "can you nail it?" rounds. No singing skill required. HOW TO PLAY 1. Record a short phrase (or sing a line). 2. Hear it played backwards. 3. Try to say that backwards take. 4. Flip your attempt—if you matched well, it sounds like the original. 5. Tap any waveform to replay. Your score is how close the flipped attempt sounds to the original (not a speech recognizer). WHY REVERSE ECHO • Built as a game: score + challenge vibe, not just a reverse button • Word + Music fun in one local party app • Works on iPhone and iPad, portrait or landscape • No account. Nothing uploaded. Your voice stays on your device. OPTIONAL Remove Ads is a one-time purchase that hides the banner.
