Everything a singer needs to stay on key
Real-time pitch detection
Start singing and the app shows your note (C, D#, F…) and its frequency in Hz instantly, with low latency.
Scrolling pitch graph
A piano-roll graph draws your pitch as you sing, so you can see wobble, slides and held notes at a glance.
Know when you are off key
The graph sits on note lanes, so it is obvious when your voice lands between notes, sharp or flat.
Record and replay
Record a phrase, then replay it alongside its pitch line to hear and see exactly where it went wrong.
Built-in metronome
Set the tempo in BPM and practise scales and phrases in time without opening another app.
Private by design
Pitch detection runs on your device. Your voice is never uploaded.
Built for daily vocal practice

Read guide →Frequently asked questions
How does a vocal pitch monitor work?
It listens through your iPhone or iPad microphone, measures the fundamental frequency of your voice many times per second and converts it into the nearest musical note. Vocal Pitch Monitor shows the note, the frequency in Hz and a scrolling graph of your pitch.
Can I use it to find my vocal range?
Yes. Slide down to the lowest note you can sing comfortably and up to the highest, and read the note names the app shows at each end. That span is your vocal range.
Does the app upload my voice?
No. Pitch detection happens on your device, and your audio is not uploaded to any server.
