Dub movies. Sing backwards. Copy any sound.

  • LINELine by line, at your own pace, every character colour-coded
  • PACEA pacing bar that turns amber the moment you run past the original
  • SCORETiming, pacing and delivery marked on every take, or switched off

Reverse Singing

Record a song and Dubloon flips it. Sing the backwards version you hear, and the app flips your attempt back. Get it right and you come out singing the real song. It is the reverse singing challenge, with a score.

  • FLIPBig simple buttons, or the full waveform with loop, speed and pitch
  • SCOREA grade for how close you got
  • KEEPSave your best takes and come back to them

  • STAYSYour video never leaves your phone unless you share it

Sound Imitation

Hear a sound, then make it yourself. A barking dog, a rooster, a car horn, a laser. Dubloon judges your rhythm, pitch and tone against the real thing and stamps a verdict on it.

  • 24Animals, horns and alarms, cartoon effects and human noises
  • VERDICTApproved or not, with a score for rhythm, pitch, tone and length
  • SHARETurn your best attempt into a video, face included

Booth Cam · Front camera

Film yourself in the booth.

Switch on the camera and Dubloon films you while you perform. Export the finished scene with your face in the corner, stacked for a story, or side by side. The camera stays off until you turn it on.

Questions

Before you press record.

How do you sing a song backwards?

Record a line of a song, play it reversed, then copy the reversed sound as closely as you can. Reverse your copy and you hear the original song again, in your voice. Dubloon does the recording, reversing and scoring for you, and the booth at the top of this page lets you try it now.

Is Dubloon free?

Dubloon is free to download and reverse singing is free for everyone. Dubloon Pro unlocks movie scene dubbing, sound imitation, Booth Cam and video exports, as a one-time purchase or a subscription.

Is there a Mac version?

Yes. On the Mac, Dubloon is an editing suite with a sidebar, a lines list, a viewer, a timeline and an inspector, and it works from the keyboard. Dubloon Pro bought on iPhone unlocks on the Mac too, on the same Apple Account.

Are my recordings uploaded anywhere?

No. Recordings, takes, booth footage and exported dubs stay on your device until you choose to share them. There is no account and no sign-up.

Which movie scenes can I dub?

Four scenes are included: Camp Rules from Sprite Fright (CC BY 4.0), Awesome in Space from Tears of Steel (CC BY 3.0), A Kindred Spirit from Sintel (CC BY 3.0) and Stuck Up from The Outsider (1951, public domain). After that you can import community dub packs from Files, Finder or AirDrop. Make sure you have the right to use whatever you dub.

Your line. Action.
