Unison: Sing in Tune

Think you can't sing? Research says you probably can. Most people who sing out of tune hear pitch perfectly well; their voice just hasn't learned where to go. Unison trains exactly that.

FIND OUT WHAT YOUR VOICE NEEDS
A free five-minute voice check measures your range, how finely you hear pitch, how accurately you match single notes, jumps and short tunes, and how clearly you can hear a tune in your head. You get a plain-English profile of what's going on and a plan built around it.

PRACTICE WITH YOUR OWN VOICE
People match their own voice more accurately than anyone else's. Unison records one relaxed "ah" and sings exercises back to you in your own voice, perfectly in tune, and it checks that this actually helps you. If you match the guide voice better, it switches. As you improve, it moves on to a guide voice and then a plain tone, so the skill works with any music.

SONGS IN YOUR KEY
Thirty songs for real moments: Happy Birthday, Christmas carols, hymns, lullabies, campfire songs, Here Comes the Bride and more, each set to your range. Learn them line by line, then sing them through from memory.

HELP THAT STEPS BACK AS YOU IMPROVE
See your pitch live in every practice, and as your accuracy holds Unison asks more of you: what counts as on pitch gets stricter, and you call low or high before you look. If you struggle, the help comes back.

A SOLO SCORE, NOT A FLATTERING ONE
A short weekly solo check, with no hints at all, shows what you can really do on your own. Watch your "with help" and "solo" lines meet.

HEAR HOW FAR YOU'VE COME
Record one line on day 1, then again each week. Unison makes a side-by-side before-and-after video, day 1 next to today, ready to share.

KIND TO YOUR VOICE
A daily singing-time limit, practice notes kept inside your comfortable range (and pulled in if they're a stretch), and a steadiness check that switches to a lighter session when your voice seems tired.

PRIVATE BY DESIGN
Your singing is analyzed on your iPhone and never uploaded. Your recordings and videos are never sent to us: they stay on your phone (and in your own private iCloud backup, if you leave it on). No account, no ads, no tracking.

SING TOGETHER
Rounds and harmony parts with the app, in your key: hold the home note under a tune, then sing a real harmony line. The step from singing in tune alone to singing with others. (Headphones on.)

TECHNIQUE AND A COACH THAT NOTICES
Breath, steady notes, smooth slides and soft-to-loud control. And a coach that spots your patterns (high notes falling flat, big jumps coming up short) and tells you how to fix them, with the exercise that trains it.

LEVELS, BADGES AND FRIENDS
Earn XP and badges, sing the weekly challenge song, challenge friends with a link, and opt in to Game Center leaderboards.

A STREAK THAT KEEPS YOU GOING
Gentle reminders, a streak widget for your Home and Lock Screen, and Siri: "Start my Unison session."
