n-Track Tuner

What n-Track Tuner is

n-Track Tuner is an instrument tuner for Android and iOS that pairs automatic note detection with a spectrum analyzer. When you play a note, the tuner indicates whether it is flat or sharp and shows when it is centered. The analyzer displays frequency content from the device’s built-in microphone and highlights the harmonic being tracked. A Diapason view plays a reference tone, and its frequency can be adjusted with a slider. The App Store listing describes use with guitar, violin, viola, cello, bass, piano, and wind instruments, along with sensitivity and precision adjustment up to 0.1 cents, alternate temperaments, and calibration for non-standard tunings. Sonogram and 3D spectrum views are Pro features. The free version costs nothing; the Pro version costs $2.99, paid once. The maker’s privacy policy says it may process contact details and technical information such as device information and IP addresses, and that personal data will not be transferred outside the European Economic Area. Support is available through a form and discussion forum; replies are usually sent within 24 hours.
