## What is Flipvox?

Flipvox is a reverse audio app built for the reverse singing challenge. Record your voice, hear it played backwards instantly, then try to sing the reversed sound back. Flipvox reverses your attempt and gives a 0-100 similarity score, so you can see how close you got to the original.

What you can do
• Reverse audio in one tap: record and play your voice backwards right away
• Similarity score from 0 to 100 with stars and playful comments
• Slow down or speed up from 0.5x to 2x, shift the pitch and loop the tricky part
• Compare original and reversed sound side by side (A/B)
• Party mode for 2 to 8 players with a local scoreboard, no accounts needed
• Reverse word game: guess the word from its backwards sound
• Voice effects: chipmunk, robot, alien, echo, reverb and more
• Reverse video: film a vertical clip with your voice played backwards
• Import audio or video files, trim them, then save or share the result
• Library to rename, favorite, search and replay your recordings

How it works
1. Record a phrase or a line of a song.
2. Listen to it backwards.
3. Imitate the reversed sound with your own voice.
4. Flipvox reverses your attempt and scores how close it is to the original.

Private by design
There is no account to create. Reversing, effects and scoring run on your device, and your recordings are not uploaded. You choose when to share a clip.
