Free online singing tools

Which one do you need?

The three tools answer three different questions, and running them in the right order saves you a lot of guessing:

• "Which notes are actually mine?" → the vocal range test. Exercises pitched outside your range make you strain and score badly for no reason. Measuring first takes a minute and makes everything after it fit.
• "What is my voice doing on this note?" → the vocal tuner. A guitar tuner gives you one needle; this draws the shape of the note, so drift, wobble and a scooped onset are visible rather than just "off".
• "Can I even hear the difference?" → the tone-deaf test. If you cannot hear a gap, you cannot sing it. The test reports the threshold in cents instead of a yes/no verdict.

No download, no software to install

Vocal training software used to mean an installer, a licence key and a desktop you had to be sitting at. None of that is necessary any more: browsers can capture a microphone and analyse pitch fast enough to draw it as you sing. Everything here runs on Windows, macOS, Linux, Android and iOS through the browser you already have, and works the same on all of them.

The only thing browsers insist on is a tap or a click before the microphone starts — a privacy rule, not a bug. Press the start button on each tool and allow access when asked.

Getting an accurate reading

1. Find a quiet room. Room noise confuses every pitch detector, including this one. It matters far more than which microphone you own.
2. Sing a sustained vowel. "Ah" or "ee" held steady reads cleanly; consonants, whispers and very breathy notes do not.
3. Get reasonably close to the mic — a forearm's length — but not so close that the signal clips.
4. Use headphones if anything is playing back, so the microphone hears you rather than the speakers.
5. Warm up before a range test. A cold voice measures short. Two minutes of sirens is enough.

When a tool stops being enough

A tool measures; it does not teach. Once you know your range and can see your pitch, the thing that actually moves the needle is repetition against a target with a score you can compare week to week. That is what the full app adds — guided drills, scoring in cents, and a history — and it is free too, with no account needed to start. Start with how to sing in tune if you want the method behind the drills.

Frequently asked

Is there a catch — will these ask for a card later?

No. These three tools and every built-in drill in the app are free and stay free. Vocalify Pro covers two server-side extras: splitting a backing track into accompaniment and vocals, and keeping more than five saved melodies. Nothing free today moves behind the plan later.

Do I need an account?

Not for any of these, and not for the app's built-in exercises either. An account only becomes useful when you want your practice history synced across devices, or want to save your own melodies and routines. See using Vocalify without signing up.

How accurate is browser pitch detection?

In a quiet room with a sustained vowel, to within a few cents — well below the roughly 10–25 cents most listeners can hear as "off". Noise, breathiness and very low notes widen the error, which is why the tuner shows the raw trace instead of pretending to a single confident number.

Can I use the tuner for an instrument?

It will track any clear monophonic pitch, so a flute or a single guitar string reads fine. It is tuned for the human voice, though, and it will not sensibly follow a strummed chord.
