Ukulele Tuner
Tune a soprano, concert, tenor or baritone ukulele - including re-entrant standard tuning and low-G.
Standard ukulele tuning is re-entrant. The 4th string (G) is tuned higher than the 3rd (C), so the strings do not run low to high the way a guitar does. That is correct and deliberate — it is a large part of why a ukulele sounds like a ukulele. Choose Low G if yours is strung the other way, and Baritone if it is tuned D G B E like the top four guitar strings.
Press start, then play a note.
The microphone is used only while you are tuning. Nothing is recorded and no audio leaves your device.
Tap a string to tune it on its own, or tap it again to hear its reference note. Leave none selected and the tuner will work out which string you played.
A4 = 440 Hz is the international standard and the right default. Some ensembles tune slightly differently by convention; no reference pitch is acoustically or scientifically superior to another.

Re-entrant tuning, explained
On almost every stringed instrument the strings run from low to high as you cross the neck. A ukulele in standard tuning does not. The fourth string - the one nearest you, the G - is tuned higher than the third string, the C. The pitches go high, low, middle, high.
This is called re-entrant tuning and it is not a mistake. It is a large part of why a ukulele sounds like a ukulele: chords ring with their notes interleaved rather than stacked, which gives that bright, close, slightly jangly sound. It is also why strumming a ukulele chord sounds different from playing the same chord on the top four strings of a guitar.
If yours has a thicker fourth string and sounds deeper, it is strung low-G. Choose that tuning instead and the strings will run low to high in the usual way.
Which tuning for which ukulele
Soprano, concert and tenor ukuleles are normally GCEA, either re-entrant or low-G. Baritone ukuleles are tuned DGBE - exactly the top four strings of a guitar - which is why guitarists find them immediately familiar. D tuning (ADF#B) turns up on older soprano instruments and in some sheet music.
Nylon strings move
Nylon and fluorocarbon stretch far more than steel, so a new set will go flat repeatedly for the first few days. That is normal. Tune, play, tune again, and expect to do it several times before it settles. They also respond to temperature, so an instrument brought in from the cold needs a few minutes and another check.

Quick answer
Choose your tuning - standard GCEA for most soprano, concert and tenor ukuleles - press start and play a string. Standard tuning is re-entrant, meaning the G string is tuned higher than the C, which is correct and deliberate.
