United StatesKeyTuner is a full-range accurate and easy to use chromatic tuner that gives clear feedback with a visual design that makes maximum use of the screen. A consistent horizontal display for fine and coarse tuning allows easy tracking of the needle as a note is played. The display is suitable for both tuning and intonation practice. Quick mode provides fast confirmation in live situations. Tone generation is also supported for droning. An advanced digital algorithm is used to allow precise tuning of all instruments (strings, woodwinds, brass, plucked string, etc). Many tuners have difficulty with low registers or those with many overtones but KeyTuner employs algorithms specifically aware of harmonic distributions. By taking advantage of the real-time behavior of multiple waveforms, vibrato can be detected and is shown as a highlighted region around the needle. Features: - Accuracy of 0.1 cent (0.001 semitone) - Works with all instruments from A0 to C8 - Large easy-to-read meter for fine tuning - Space efficient display for coarse tuning - Quick mode for easy adjustments - Color schemes: Light, Warm, Dark - 3 levels of needle dampening to control responsiveness - Temperament selection: Just, Equal-Tempered, Strings - Supports transposing instruments - Tone/drone generation - Concert Pitch (A4) calibration
The most accurate tuning app I’ve tried
I have used lots of tuning apps.This one is the easiest to use and the most accurate.
United StatesVery nice - Zero price
Very sensitive. Auto key sense. Cents up or down on separate meter. Will make my go to tuner.
United StatesIncorrect
I have perfect pitch. It is always a half note down from the real note.
United StatesExcellent Tuner
Settings for different instruments, cents ranges can be set, other great options. Highly recommended by a retired piano tuner and band director. Even though it does not do the octave stretching required to tune pianos well, it does everything else So Well.
United StatesBest tuner ever plus no more 1032 hearing aid batteries
I love this tuner and the fact that it has a micro range for fine-tuning. I use it on all of my instruments, guitar, mandolin and octave mandolin for many years I have used the clamp on tuners that take batteries. they’re always dead and not particularly accurate. Plus they’re hard to read with KeyTuner on your iPad, I iPad mini or phone, you have an accurate easy use always ready tuner. I’ve recommended this to many of my fellow musicians (the ones that like to be in tune).
United StatesEasy and trustworthy
Turn it on (open the app) select the instrument. Tune. Done Now PRACTICE and make beautiful music.
United StatesVery good tuner!
As a lifelong musician and a professional accordion tuner for the last 15 years, I have used many tuners and apps. This one is the best and it even has an accordion algorithm. Some of the more expensive tuners don’t even approach the practicality of this app because they don’t show cents! What’s up with that?! Anyway, this is an infinitely useful app. Thank you!
