About

Centz

Features
Read full description

Centz is a tuner that gets out of your way. Point it at your instrument, play a string, and a single focused LED-style meter tells you exactly what you need to know: flat, in tune, or sharp. No clutter, no menus to dig through — just fast, accurate tuning whether it's your first week or your next gig. THREE WAYS TO TUNE • Auto — Just play. Centz snaps to the nearest open string and shows how far off you are. Perfect for quick top-ups between songs. • Guided — Centz walks you through every string, lowest first, marking each one off as it lands in tune. The methodical way to tune the whole instrument. • Manual — Tap the string you want, and Centz measures against that one only. Ideal when a string is badly out and you want full control. BUILT FOR PLAYERS WHO TUNE A LOT OF THINGS Guitar, bass, ukulele and banjo — and now violin, viola, cello, double bass and mandolin, 7-string, 8-string and baritone guitars, the 12-string, and the tenor ukulele. Switch instruments in a tap. Each one carries its own tunings, so alternate setups aren't buried in settings. OR NO INSTRUMENT AT ALL Pick Chromatic and Centz listens for any pitch at all, names the nearest note and shows how far off it is — no instrument chosen, nothing assumed. Anything that sounds a pitch between 28 Hz and 1.5 kHz. STANDARD TUNING, FREE. ALWAYS. Every instrument has a free standard tuning, forever — open G on the banjo. Unlock the rest with Centz Pro: sixteen alternate tunings, twelve for guitar alone — Drop D, DADGAD, Drop C, Drop B, Eb standard, Double Drop D and the open family. One payment, no subscription. TUNE TO YOUR REFERENCE Concert pitch is fully adjustable. Tuning to A=432 instead of A=440? Playing alongside a piano that's drifted? Set the reference and every string follows. ACCURATE TO THE CENT Centz measures pitch error in cents and treats you as in tune within a tight tolerance — close enough that the meter agrees with a trained ear, every time. DESIGNED TO BE GLANCED AT A clean, distraction-free interface that reads instantly under stage lights or on the couch. Everything is analysed live through the microphone and never recorded, so nothing leaves your phone. Download Centz and spend less time tuning, more time playing.
