Backvox: Reverse Singing App

Backvox is a reverse singing app and reverse audio tool for your voice. Record a line, hear it backwards straight away, then try to sing the reversed sound and flip your copy back to see how close you got.

QUICK REVERSE
• Tap to record and hear it reversed in a second
• A simple reverse voice recorder: record, flip, then save the clip
• Speed from 0.5x to 1.5x, pitch Deeper, Normal or Higher
• Loop, trim, save or share the reversed audio
• Your reverse voice plays at the speed you recorded it, unless you change it
• Sing a few lines and turn them into a reverse song
• Import an audio file from your phone and reverse it (up to 30 seconds)

THE REVERSE SINGING CHALLENGE
1. Record a short line: a name, a tongue twister, a song you sing yourself.
2. Listen to it backwards as many times as you like, slower if it helps.
3. Copy the backwards voice and record your best imitation.
4. Backvox flips your copy back and gives a score from 0 to 100.
The score is worked out on your phone by comparing the two sounds. The funny part is hearing your flipped copy next to the original.

PLAY TOGETHER ON ONE PHONE
Add 1 to 4 players and pass the phone between turns. After 3 rounds the highest score wins. Playing alone? Play solo and beat your best.

SHARE THE FUNNY PART
• Share a 9:16 video with both voices as waveforms and the score, ready for short video apps
• Or share the reverse audio only, as M4A or WAV
• Free videos carry a small Backvox mark; watch one short video to remove it from that video

YOUR LIBRARY
Recordings and challenge rounds are kept in a Library on your phone. Search them, replay them, or share them again later. There are no built-in songs: every sound in Backvox is one you record or import.

ADS THAT WAIT THEIR TURN
No ads before your first recording, and never while you record or play. Free users see a banner in the Library and at most one full-screen ad every 3 challenge rounds, only after a score screen.

Recording, reversing, challenges and sharing stay free. With Pro you get:
• No ads

PRIVATE BY DESIGN
No account and no sign-up. Recordings stay on your phone and are never uploaded. Backvox only uses the microphone while the app is open and you tap record.
