Strobe Tuner Pro is the only tuner that shows the real stroboscopic effect on your device. It is extremely accurate, suitable for guitar, violin, bass, ukulele, viola, cello, banjo or shamisen. By purchasing it, you can save hundreds of dollars for a physical strobe tuner. Professionals appreciate the Strobe Tuner Pro's accuracy, beginners quickly learn to tune instruments properly. Strobe Tuner Pro is easy to use thanks to an additional chromatic tuner that helps you when your instrument is way out of tune. The chromatic and strobe tuners are independent, but both use the same input from the built-in microphone of your phone or tablet for their advanced algorithms. Chromatic tuner The chromatic tuner accurately detects the frequency of the tone played on your instrument, and shows it on the chromatic scale. The target strings are highlighted on the scale, and you can see how far is the tone from being in tune. When you get close enough, you can use the strobe tuner for fine tuning. Strobe tuner When the pattern is rotating to the right, it means the tone is too high, and you need to tune down. When it is rotating 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. The algorithms of both tuners are independent - the chromatic tuner uses the Fast Fourier Transformation, but 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. Tuning by ear You can also play the reference tones using the buttons at the bottom of the screen. The tone is synthesized, and respects the setting of the concert pitch. Instruments The tuner has been tested with many guitars, violins, basses, ukuleles, violas, cellos and banjos, and we constantly grow our test coverage with new recordings of the instruments. You can switch between the guitar and the violin tuning in the settings. Metronome The tuner also features a built-in metronome, combined with a chromatic tuner. This makes practicing much easier - you can control the metronome and check the intonation at the same time.
