How accurate is the pitch detector?

Our tool is highly accurate, with a precision of within ±5 cents of a note. It uses the industry-standard YIN algorithm for reliable, real-time analysis suitable for both musicians and audio professionals. For more details, see our accuracy tests .

Is my audio data private and secure?

Absolutely. Your privacy is our top priority. All audio processing is done locally in your browser. No audio is ever recorded, stored, or sent to a server. You can read our full data security policy for more information.

The detector isn't working. What should I do?

First, ensure you have granted microphone access in your browser. If it's still not working, try using a quiet, echo-free environment and holding a clear, steady note. For a complete list of solutions, please visit our troubleshooting page .

What are 'cents' in music?

A 'cent' is a unit of measurement for musical intervals. There are 100 cents in one semitone (the distance between two adjacent notes on a piano). Our meter shows how many cents sharp (positive value) or flat (negative value) your note is, allowing for very precise tuning.

What is the difference between pitch and frequency?

Frequency is the scientific measurement of a sound wave's vibrations per second, measured in Hertz (Hz). Pitch is the musical term for how high or low a note sounds to our ears. While they are related, pitch is a subjective perception, whereas frequency is an objective measurement. Learn more in our glossary .

Can I use this to tune my guitar?

Yes! This tool works perfectly as an online guitar tuner. Simply play each string one at a time and use the feedback to adjust the tuning pegs until the note is perfect. It works for acoustic and electric guitars (if played through an amplifier).

Best Pitch Detection App for iPhone & Android: A Singer’s Guide

If you want an all-around pitch detection app, Nail the Pitch – Vocal Monitor stands out for both iPhone and Android. For Android-only, Vocal Pitch Monitor is a popular free option. On iPhone, Pitch Checker and Singscope provide clean visual feedback, while Vocaberry helps map your vocal range.

Why Use a Pitch Detection App?

Singers use pitch detection apps to:

Check if they’re singing in tune during practice.
Track vocal range (lowest to highest note).
Visualize pitch in real time with graphs or piano layouts.
Record and review practice sessions to hear progress.

Unlike standard tuner apps designed for instruments, vocal pitch apps handle vibrato, slides, and voice texture better, making them more reliable for singers.

Practice in a quiet space: background noise can throw off accuracy.
Use an external mic if possible: cleaner input means better results.
Start with steady notes before testing scales or vibrato.
Record sessions to track improvement over time.
Pair with ear training: apps give feedback, but your ears do the real learning.
