About this app

Tuneo, also knows as "Guitar and Violin Tuner" is an extremely accurate instrument tuner for many instruments, like guitar, violin, bass, ukulele, viola, cello, banjo and shamisen, including many alternate tunings and variants.

Professionals appreciate its precision, beginners quickly learn to tune their instrument properly. The application is easy to use thanks to a combination of a chromatic and a strobe tuner on one screen, and provides the most accurate tuning you can achieve.

The chromatic tuner precisely detects the frequency of the tone played on your instrument, and shows it on the chromatic scale. The target pitches are highlighted on the scale, and you can see how much is the tone out of tune. When you get close enough, you can use the strobe tuner for fine tuning.

The strobe tuner helps you to achieve extreme accuracy. The pattern is moving to the right when the tone is too high, indicating that you need to tune down. When it is moving to the left, just tune up. The slower the pattern moves, the better is your instrument tuned.

If you are in doubt how to use the tuner, please read the built-in help, and see the examples of the tuning process there.

The strobe tuner uses an independent algorithm from the chromatic tuner. While the chromatic tuner uses the Fast Fourier Transformation, the algorithm in the strobe tuner is much closer to what you can find in oscilloscopes, and is computed directly on the GPU of your phone or tablet.

You can also use the tuner to tune by ear. The buttons at the bottom of the screen play the reference tones and you can tune accordingly. The tones are synthesized, and respects the setting of the concert pitch.

The tuner has been tested with many guitars, violins, basses, ukuleles, banjos and shamisens.

I will miss this app, it has been a staple of my music room for years but I just realized it was tracking my location and sharing it with third parties which is unreasonable behaviour for a guitar tuner. I can't be mad I should have read the fine print. Lesson learned, and I'll be suggesting a replacement for all students. Left two stars for solid performance.

Easily the most accurate I've been able to find (unfortunately an absolute necessity for my low skill level). My favorite guitar sometimes has a tendency to lose tone on certain strings and specific points on the neck, and this helps me find the middle ground so I can try and keep it consistent. Very, very good for beginners or anyone with suspected similar issues. Pros may or may not need help, but this would be an excellent tool to validate tones/tuning even at that level.

Worked better than I expected actually. The little weird moving shape things depicting harmonica or whatever might take me a minute to get used to but the usual tuners are excellent as far as I can tell. Tuned up to it many times and had no issues with it on my phone whatsoever. fast and accurate and reliable. Would highly recommend. FIVE STARS!!
