About this app

The
best free tuner app for guitar, bass, ukulele, violin or string instruments.

Downloaded by over
1 million users! - a must-have in your musical toolkit!

Tune your guitar, bass or other instruments with the free n-Track Tuner in two simple steps:

1) Put your device next to your instrument and play each string

2) The tuner will automatically recognize the note you're playing and tell you whether you need to lower (green bar) or increase (red bar) the string's pitch.



FREE ADVANCED FEATURES

•||| Spectrum Analyzer |||•

The audio spectrum analyzer provides visual feedback of the notes played by the instrument and shows a small arrow to highlight the harmonic whose pitch the tuner is tracking.

•||| Diapason |||•

For those who prefer to manually tune their instrument, the 'Diapason' view lets you play a reference tone, 'A' (440 Hz) or any other note that you can select by moving the frequency slider.


ADDITIONAL FREE ADVANCED FEATURES:

• Tap to adjust the Spectrum Analyzer Visualization options, select thicker Spectrum Lines, smooth out or highlight peaks, increase or decrease tuning sensitivity and precision (up to 0.1 cents)

• You can calibrate the tuner for non-standard tunings: tune the reference note, tap on the display and select 'Calibrate' to set the note as the new reference. You can also select non-standard musical temperaments & alternate note naming conventions.

• Select the Sonogram tab to view how the frequency spectrum changes with time, and follow the tuned note as it travels through the spectrum as a green line

Used this app for years to help with speech therapy. I downlaoded many other tuners, but this one has always been my favourite. It picks up sound easily, and accurately jumps to the correct Hz. It's also easy to see when I'm not holding a note steady because of the long and stable Hz meter (other apps can jump all over the place and it makes it hard to read). Thanks for the great app!

Something is seriously wrong with my tuner. Loved this on my ios tablet so got the paid version. When I switched my phone to android (s7) this app is woefully disappointing. I use this app for violin, ukulele, sax, guitar... and its been very clean and clear with useful settings. Paid for the android version hoping it would come good... no luck. please contact me or push out an update

It's not working. After opening it, it crashes: "n-track tuner has stopped!" I already uninstalled and installed again a couple of times and same thing... It works fine on an old LG phone. In this Moto es6 I'm using nowadays it used to work as well, just in the last days it haven't been working anymore. After allow the app to record audio, in the first execution the problem starts, black screen and the message just mentioned above. Is is possible that an update is bugged? ...
