The piano plays a short pattern, you sing it back. Your voice shows up as a line on a piano roll: green when you land on the note, yellow when you're close, red when you're off. 171 exercises, from a five-minute warm-up to belting, in 27 languages.
In Chrome, Edge or Safari on a computer or a phone, or in the iPhone app. Put on headphones so the piano doesn't leak into the mic. Audio is analyzed on your device and never uploaded.
While you sing, your voice is drawn as a line across the target notes. Green means you're on the note, yellow means you're a little off, red means you're far off. A finished note gets a colour and a percentage, so you don't have to wait for the end to know how it went.
Lip trills and sirens to warm up, scales, arpeggios and intervals for intonation, mixed voice exercises for the top of your range, pentatonic runs, breath control and long notes with vibrato, ear training, and short melodies with lyrics. Everything is transposed to your vocal range.
Daily training picks exercises for your level and range. Exercises come in three difficulty levels. Scores, your streak and the highest note you sang cleanly are saved, so after a few weeks you can see whether the top of your range is actually moving.
The pitch analysis runs on your device – in the browser or the iPhone app – and your voice is never uploaded. You don't need an account: progress is saved on the device. Sign in only if you want the same progress on your phone and your computer. No ads.
Headphones matter more than the microphone: without them the piano comes back through the mic and muddles the tracking. The built-in mic in a laptop or phone is fine to start. A USB microphone or an audio interface (a Focusrite Scarlett, for example) with a dynamic or condenser mic tracks pitch more cleanly; you pick the input device and channel in Settings.
Pick a voice type or take the two-minute vocal range test. Then the piano plays a short pattern, you sing it back and watch your line land on the blue blocks. Exercises are transposed so every note sits inside your range.
Each note gets a verdict: in tune, flat, sharp or unstable. At the end you see a percentage and a short tip, for example that you were 20 cents flat on the high notes. How strict the scoring is you set yourself, from ±20 to ±100 cents (default ±50).

No. You hear a pattern and sing it back; the target notes are blocks on a piano roll, not notation. Note names are shown on the side if you want them.
The one built into your laptop or phone works. If you have a USB microphone, or an audio interface such as a Focusrite Scarlett with a dynamic or condenser mic, the pitch tracking is cleaner and less bothered by room noise. You pick the input device and, on an interface, the channel in Settings. Headphones matter more than the mic, though: without them the piano leaks back in.
Yes. On iPhone there is the Clearsing app in the App Store, and the web version also works in Safari. On Android, use it in the browser (Chrome or Edge) – there is no Android app yet. On a computer, use Chrome, Edge or Safari. You can add the web version to your home screen.
No. The pitch detection runs on your device – in the browser or in the iPhone app – and the audio never leaves it. The only recording is the one you can play back after an exercise; it stays in memory and disappears when you leave the exercise. If you sign in, your results and settings are stored with your account, never your voice.
No. Without one, progress is saved in the browser on this device, and clearing site data clears it. Sign in with Google, Apple or an email link and your results, personal bests, vocal range and daily training follow you to every device where you're signed in. You can delete the account at any time in Settings.
Take the vocal range test in Tools; it takes about two minutes. You sing a low note, then a high one, and the app finds your comfortable limits. Every exercise is then transposed to fit that range. You can also pick a preset such as tenor or alto and measure later.
On a steady tone, within a few cents (a cent is a hundredth of a semitone). The detector listens roughly between 60 and 1100 Hz, bass to soprano. The scoring tolerance is yours to set, from ±20 to ±100 cents; the default is ±50, half a semitone. Glides and lip trills get a wider tolerance on purpose.
