Record, hear it backwards, sing it back, then flip your take to check yourself.
Record your voice, hear it backwards, then sing the backwards version — and flip that back
to hear how close you got. That last step is the whole game, and it is the one thing the
other reverse apps leave out.
■ Stack voices that actually line up
Sing over your own take and the app plays it in your ears while you record the next voice.
It reads your device's audio clocks and shifts the new layer by the exact number of samples
it measured, so harmonies land together instead of drifting apart. Four-beat count-in,
headphones recommended. Bring your own backing track, undo the last layer, set its level.
■ Tap once and you are recording
The first screen is the record button. No language picker, no four-page tour, no ad before
you have done anything. The microphone permission is asked when you tap record.
■ Flip it back — the step that makes it a challenge
1. Record a sentence.
2. Listen to it backwards.
3. Sing the backwards version out loud and record that.
4. Flip your attempt — and hear your original sentence come back.
All four takes sit on one screen so you can play them side by side.
■ Play a round, and find out how close you got
Five lines a round, short or long, your pick. Say one, hear it backwards, sing the
backwards version, and the app scores how close your flipped take came to the original.
It compares the rhythm and the pitch of the two takes, on your phone. It does not check
your words — there is no speech recognition here. Clear lines to keep a streak going.
■ Too hard? Break the line into pieces
One tap splits the backwards line into short pieces and loops each one, so you learn it a
piece at a time instead of giving up.
■ Pass the phone
Switch it on and the line is hidden. One person records it, the next hears it backwards and
guesses, and you show the line when they give up. You decide who got it. Every line is
written by us, so nobody has to know a particular song.
■ Make a video out of it
Turn a take into a vertical 1080x1920 video with its waveform and title burned in, ready
for short-form posts — no watermark and no export limit.
■ Everything stays on your phone
No account, no upload. Send a voice message here from a chat app and it arrives ready to
reverse. Reversing, flipping, scoring and video all run on the device, so it works in
airplane mode. Recordings stay in the app until you delete them.
■ Seventeen voices that actually run
Chipmunk, Balloon, Giant, Monster, Little kid, Robot, Alien, Bee, Chopper, Megaphone,
Old phone, Radio, Echo, Cave, Underwater, Ghost, Wobbly, Shivery — all worked out on your
phone, with no signal needed. The shared file carries the voice you picked, at the same
volume as the take you recorded.
■ What you also get
● Speed and pitch from 0.5x to 2.0x, both baked into the file you share
● Loop playback, so a short reversed line repeats while you learn it
● Trim a take down — the original stays in your library
● Import a sound already on your phone and hear it backwards
● Export as WAV or M4A, or save straight to Downloads
● A library with play, reverse, rename, multi-select and delete
● A new challenge line every day, written by us — and one reminder a day if you want it
● Rounds remember your best streak, and a round's takes are saved under their line
● Saving and sharing your own recording are not locked behind anything
■ Honest about ads
Ads keep this free. One full-screen ad when the app opens, and at most two more a session —
only after you finish sharing or exporting, never in the first minute, and never while you
record or on the result screen. The recordings list shows one ad. No weekly subscription
and no free trial that turns into one.
■ Good to know
● Recording length is capped at 10 minutes per take.
● Takes are kept as raw audio and written out as WAV or M4A when you share.
● Saving to Downloads needs Android 10 or newer; below that, use the share sheet.
● This app does not include any songs. You record your own voice.
