Practise with your own song. Hit every note with your voice.
Cantavo takes a song you love, separates the vocal from the instruments and extracts the notes the singer sang. As you sing, your pitch is drawn live over those notes — you see where you land and where you drift before you hear it.
Closed beta in progress. Two of your own songs analyse for free; beyond that, Cantavo Pro is unlimited.
Four steps
No fixed catalogue to pick from — you bring the song you actually want to work on.
Bring your song
Any audio or video file on your phone. Cantavo separates the vocal from the instruments and extracts every note the singer sang.
Watch the notes flow
Target notes scroll across the screen as the song plays. Fade the guide vocal down as you get comfortable — then turn it off entirely.
Sing it
Your pitch is drawn live as a red trace over the target notes. Notes you land turn green and your score updates as you go.
Drill what you missed
Tap a note you dropped and the Workshop builds sustain, glide and interval exercises around it. Loop the phrase and run it again.
What's in the practice room
Cantavo isn't a game. It puts the controls a singer actually reaches for within thumb's reach.
Four stems, one mixer
Vocals, drums, bass and everything else on separate faders. Pull one back, push another forward, or go full karaoke.
Your key, your tempo
Transpose ±6 semitones to fit your range. Practise at 0.75x or 0.5x with the pitch held steady.
Studio and autotune
Every take is captured. Compare raw against tuned, dial the correction in gradually, A/B them live, export the result.
Exercise workshop
Sustain, glide, ladder and interval drills. Explore your range freely, or target the exact notes a song keeps costing you.
Do-Re-Mi assessment
A four-level measurement set tells you where your voice actually stands. Daily warm-ups and streaks keep you at it.
Duet and choir
Stack harmonies in your own voice, add a duet layer, and export the result as a pitch-traced video.
Your voice stays yours
The short version is below; the full text is in the Privacy Policy.
The microphone never leaves the device
Pitch analysis runs inside your phone. What you sing is not sent to a server, not stored by us, not shared with anyone. Your takes live on your device only.
Uploaded songs are temporary guests
The file sent up for analysis is deleted from the server the moment the result lands on your phone. If anything goes wrong, an automatic sweep removes it within 14 days at the latest.
An account is optional
Core functionality works without signing in. If you do create an account, you can delete it from inside the app in one tap.
