Guitar Tuner, Violin: Tuneo

Tuneo, also known as "Guitar and Violin Tuner," is a highly accurate tuning app for a variety of string instruments including guitar, violin, bass, ukulele, viola, cello, banjo, and shamisen. It combines a chromatic tuner with a strobe tuner on one screen, allowing users to achieve the most precise tuning possible. Whether you are a beginner or professional, Tuneo guides you through the tuning process with built-in help and a first-start tutorial.

Featuring advanced noise cancellation, support for alternate tunings, and synthesized reference tones, Tuneo ensures ease of use even in noisy environments or with a metronome active. The app utilizes two independent tuning algorithms—one based on Fast Fourier Transformation and the other emulating a stroboscopic effect computed on your device's GPU—to deliver quick and accurate tuning results. With adjustable concert pitch settings and multilingual note naming options, Tuneo is an indispensable tool for musicians seeking perfect pitch and optimal sound quality.
