canta
Español
Learn to sing in tune.
canta listens through your microphone and tells you, note by note, whether you're in tune. No accounts, no third-party ads, works offline, and nothing collected about you.
What it does
It starts by measuring your vocal range — your lowest and highest note — and places every exercise at the pitch that fits your voice, not someone else's. Then it guides you along a path of lessons that begins with holding a single note and reaches fifths, octaves, chromatic scales and agility runs.
While you sing you see your voice drawn against the target note, in real time. When you finish you get a score, your average deviation in cents, and one concrete piece of advice: whether you're consistently flat, whether the leap is what's tripping you up, whether long notes drift at the end.

About your voice's health
The voice is a muscle and it can be injured by overuse. canta keeps track of how many minutes you've been singing and suggests a break at twenty, calling the session done at forty, and a day off after a week straight.
That's why the app's points have a daily cap: past that point, singing more earns nothing. It would be incoherent to warn you to stop and reward you for continuing. And there's an achievement you earn by resting.
canta is not a substitute for a teacher or a voice doctor. If singing hurts, if you go hoarse or notice you're losing your voice, stop singing and see a professional.
