Reverse Audio – Sing it Backwards!
Turn any lyric into a hilarious, brain-twisting challenge. Reverse Karaoke records your voice, plays it backwards, and lets a friend try to imitate the reversed line—t
hen flips their attempt back to normal for the big reveal. It’s the perfect party game, music practice tool, and audio playground rolled into one.

What it does:
- Record yourself singing a short line from a song (or say any phrase).
- Play your recording forward to check it.
- Play in reverse to hear the line backwards.
- Hand the phone to a friend: they record themselves mimicking the reversed audio.
- Flip their take back to normal and laugh at the results!

Why you’ll love it
- Ultra-simple design: Three giant buttons—Record, Play, Play Reverse—each takes up a third of the screen. No clutter. No confusion. Just tap and go.
- Creative controls: In Settings, adjust playback rate (slow down to learn a tricky melody, speed up for fun), pitch shift (transpose up or down), and loop playback for practice or performance.
- Instant fun for two (or more): Pass-and-play gameplay makes it perfect for parties, family nights, classrooms, and jam sessions.
- Great for musicians: Practice ear training, experiment with backwards phrasing, explore backmasking effects, and hear how timing and articulation change when reversed.
- Audio sandbox: Try tongue twisters, iconic movie quotes, or your favorite chorus. Reverse Karaoke turns them into fresh vocal puzzles.
- On-device recording: Works offline. No account. No sign-in. Your audio stays on your device

How to play (classic 2-person mode):
Person A taps Record, sings a short line, taps Stop.
Tap Play Reverse and let Person B listen to the backwards version.
Person B taps Record and imitates what they hear (the reversed line).
Tap Play Reverse on B’s recording—hear the magic when it flips back!

Tip: Use Loop in Settings so the reversed line repeats while Person B practices. Lower the playback speed (e.g., 0.75×) to learn tricky syllables, then bring it back to 1.0×.
