Pico is a tiny cat who pings you a few times a day for a one-minute workout: sing the note you see, then name the note you hear. Each note has its own color, so pitches you could never name start to feel as familiar as faces.
That's a whole session: two rounds, one cat, and a habit your ear can feel.
Pico shows a note card without playing it, so the pitch has to come from your head. Sing or hum it and Pico stops recording on his own once you hold a steady tone. Then you hear your actual take next to the target, with feedback down to the cent.
Pico plays one note, and you can hear it twice. Tap the key you think it was; your first pick is final. Every key wears its note’s color, so sound, color, and name get filed away together. These keys work, by the way.

Pick the times and the weekdays, and Pico handles the remembering. He rotates through 25 different nudges so the reminders never feel canned, and none of them guilt-trip you.
Time to train your perfect pitch! 🎵
Sing one note. That’s all. 🎤
Your daily dose of pitch ☕️
Every round lands in your history, down to the cent. A 14-day Ear Score chart shows your accuracy trend, your streak feeds the flame, and XP walks you up seven cat ranks toward Pitch Master.
Pico's training library pairs ten famous openings with the note each one starts on, played on a real sampled piano. Pico will happily loop just the first note until it's glued into your memory. Tap a piece to hear its anchor note.
Perfect pitch is two skills stacked: remembering a note, and knowing what to call it. The first one you've been practicing your whole life without noticing. Pico's job is the second one.
In a 1994 study, 44% of people with no special training sang a favorite song in the original key on at least one of two tries. Researchers call it the Levitin effect; follow-up labs found it again, smaller but real.

The honest part: an adult brain rarely grows flawless, inborn-style perfect pitch, and Pico won't pretend otherwise. It doesn't need to. Anchor a handful of notes, lean on relative pitch for the rest, and the gap keeps closing with every one-minute session.
Every note in Pico wears a fixed color, in the app and on this page. Color gives your memory a second handle on the same sound: as the app puts it, once you know the rainbow, "hearing a note feels like seeing one."
Every round pays XP, and XP walks you up seven cat ranks. Along the way there are 21 trophies to collect, from quick wins to feats your choir director would raise an eyebrow at.
Nothing gets lost. Your XP, streak, trophies, and even the hat you put on Pico ride along in iCloud. New phone, same cat, same progress. No account, no login.
One subscription, all of it. Unlimited pings, full history, every trophy, and Pico's entire wardrobe of colors and hats. There is no locked tier behind the cat.
Onboarding is a chat with a cat. Before the tour is over you’ve sung a C from memory into the mic, and Pico calls it your home note.
One to five reminders a day, your times, your weekdays. Change them whenever; Pico keeps up.
When a ping lands: sing one note, name one note, done. Streaks and trophies handle the wanting-to-come-back part.
That's the whole loop. Pico handles the reminding, you handle the minute. Tomorrow, again.
True inborn perfect pitch is mostly set in early childhood; the research is clear on that, and Pico won’t tell you otherwise. What adults can train is the useful part: recognizing notes faster, anchoring specific pitches in memory, and bridging the rest with relative pitch. With daily practice, you’ll start naming notes that used to be a mystery.
Two rounds, about a minute. Round one: Pico shows a note card and you sing the pitch from memory; recording stops on its own once you hold a steady tone, and you get your take played back next to the target. Round two: Pico plays a mystery note and you tap it on the rainbow piano. You can hear it twice, and your first pick is final.
You need to hum, at most. Pico scores the pitch, not the performance: sing, hum, or whistle, and the detector follows you from a low voice to a high whistle. It’s octave-forgiving too, so matching an E in your own comfortable range counts.
No. Pico plays every note for you, and Sing rounds need only your voice and the phone’s mic. Your recordings are analyzed on the device, just for pitch detection.
You decide: one to five pings a day, at your times, on your weekdays. Pico rotates through 25 different messages so they stay fresh, and none of them guilt-trip you. Miss a day and he just suggests starting again.
Pico is a subscription, billed through Apple: $9.99 a year after a 3-day free trial, or $1.99 a week. One subscription covers everything in the app, the trophies, the training library, and Pico’s entire wardrobe included.
It moves with you. XP, streak, history, trophies, and even Pico’s outfit sync through iCloud automatically. There’s no account to create and nothing to back up.
Pico is out now on the App Store for iPhone (iOS 17 or later). Tap any of the App Store buttons on this page, or search for “Pico: Train Perfect Pitch”.
