canta: learn to sing in tune

canta listens through your microphone while you sing and tells you right away whether you are sharp or flat. When you finish it does not just hand you a score: it explains what to fix.

Free, no third-party ads, no account. You do not need to read music.

WHAT MAKES IT DIFFERENT

Most singing apps give you a number and leave you where you started. canta looks for patterns in what you sang and names the cause:

• "You are consistently flat" — and where to aim instead
• "Big leaps give you more trouble than stepwise notes"
• "Your long notes sag towards the end: you are running out of air"
• "You are singing the right note, but an octave below"

Then you see a note-by-note chart: exactly where you were in tune and where you were not.

IT FITS YOUR VOICE

First you measure your range by singing from your lowest note to your highest. Every exercise is then placed inside that range, so it never asks for notes you cannot reach. It also tells you which voice type yours resembles: bass, baritone, tenor, contralto, mezzo-soprano or soprano.

SHAPED LIKE A REAL LESSON

Demanding exercises are never done cold. The routine walks you through the order any teacher uses: breathing, lip trill, humming, the technique of the day, and cooling the voice down at the end.

• 3 levels and 11 lessons, in a graded order and all open from the start
• 12 vocal exercises: sustained notes, scales, arpeggios, thirds, fifths and octaves, agility, chromatic
• 4 diaphragmatic breathing exercises that measure support and airflow
• 7 complete melodies, public domain or original, transposed to your voice
• Reduced speed at 60% or 80% to study what does not come out yet

IT LOOKS AFTER YOUR VOICE

The voice is a muscle. canta keeps track of how long you have sung today and suggests stopping when it is time, and taking a day off after several in a row. Points are capped daily on purpose: past that point singing more earns nothing, so nothing pushes you beyond a healthy session.

YOUR PROGRESS

Day streak, session history, and a comparison between your recent sessions and the ones before, so you can see whether you are actually improving.

YOUR AUDIO NEVER LEAVES YOUR PHONE

Sound is analyzed on the spot, on your device, and thrown away. Nothing is recorded, nothing is uploaded, canta has no backend of its own, no account, no third-party ads and no trackers.

At the bottom of "Your voice", optional recommendations include naeku.io, ytrocket.com, Dismusic and Pulso, from our team at PDEVELOP. They open service websites or app information pages only when you tap them. They do not unlock features, and canta sends them no practice audio, account identifiers or tracking parameters.
