Record
Tap the recording card and speak a phrase, joke, name, or challenge for your friends.

Three simple steps
From your voice to a backwards surprise.
The core experience stays focused: capture a sound, reverse it locally, and listen to the difference.
Reverse
The app creates a frame-correct reversed WAV copy directly on your device.
Compare
Play the original and reversed clips side by side, then share the result when you choose.
Built for quick fun
Everything you need for the next voice challenge.
No complicated editing timeline. The controls stay large, clear, and ready for another take.
Instant original vs. reverse
Switch between both directions and hear exactly how your phrase changed.
Local recording history
Keep recent originals and reversed clips together in an app-private library.
Share only when you decide
Send a selected reversed WAV through Android's system share sheet.
Easy cleanup
Delete both versions of a recording with a clear confirmation step.
Try something different
Small recordings. Big reactions.
Reverse-speech challenge
Guess what a friend said, then play the original to reveal the answer.
Funny voice moments
Flip names, catchphrases, and everyday sounds to discover unexpected results.
Sound experiments
Compare rhythm, syllables, and short musical ideas from a new direction.
Private by design
Your recordings stay on your device.
The current app has no account, cloud sync, advertising SDK, or analytics SDK. Audio leaves the app only when you deliberately choose to share a recording.
- Contextual microphone access
- App-private local storage
- No developer audio upload
- Delete recordings in the app
Questions
Good to know.
Why does the app need microphone permission?
Microphone access is required only to record the sound you ask the app to reverse. You can deny or revoke permission in Android Settings.
Does my audio get uploaded?
No. The current build processes and stores recordings on the device. A selected file leaves the app only when you use Android sharing.
Do I need an account or internet connection?
No account is required, and the recording and reversal features work offline.
How do I remove recordings?
Use the recording options to delete a clip and its paired original. Uninstalling the app also removes app-private recordings under normal Android behavior.
