Five pumpkins, five faces, one song. Made with Sync-o’-Lantern.

Halloween app for iPhone and Android

Make your pumpkins sing.

Choose a song on your phone and Sync-o’-Lantern lip-syncs up to six glowing jack-o’-lantern faces to the singer. Point a projector at real pumpkins and your porch puts on a show.

Free to download. One in-app purchase unlocks whole songs.

Features

How it works

From song file to front porch

Everything happens on your phone. No computer, no account, no per-song fees.

  1. Pick a song

    Choose an audio file on your phone: MP3, M4A, WAV, FLAC and more. The app separates the singer’s voice from the band right on the phone, so mouths open on the vocals, not the drums. Have a timed lyrics file (.lrc)? Add it to decide exactly who sings each line. No song handy? Try our demo song.

  2. Cast your pumpkins

    Choose how many pumpkins sing, from one to six, and give each one a carved face. Then choose how they share the song:

    Auto
    Solo lines take turns; lines sung by several voices are sung by every pumpkin.
    Turns
    Pumpkins take turns, handing over only between sentences.
    Together
    Every pumpkin sings every line.
    Solo
    Pumpkin #1 sings while the others sway to the music.
  3. Start the show

    Play a live show full screen through a projector, in sync with the music, or make an HD video to save and share. Feeling brave? Sing into the microphone and the pumpkins sing along with you, live.

The Sync-o’-Lantern setup screen: five pumpkins in Auto mode, a lit preview of five carved faces, and a face picker for each pumpkin.
