What is KeyTuner?
KeyTuner is a chromatic tuner app that is designed to provide accurate and easy tuning for all types of instruments. It features a clear and easy-to-read display that makes use of the entire screen, allowing for fine and coarse tuning. The app is suitable for both tuning and intonation practice, and it also supports tone generation for droning.
- 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
this app 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 this app 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.

UPDATE: Not only did they respond to my review, but they FIXED the issue as well, and within a couple of DAYS of posting my review! Great job, developers!!! 😃👍 Original review: This is an awesome tuner, but the only thing I have an issue with is that the letter keys to audibly hear the sound are not transposed. In Alto Sax mode (Eb), when I tap the A# key, it is audibly playing a G. However, the microphone is synced up with the correct key; when I play a G note, it displays the G. I’ve tried adjusting settings and have not found a solution to this issue. Please fix this, and I will change my review to 5 stars because I like this app, but I want to love it! 😊

Found an OLD Wurlitzer piano in the garbage. I never tuned a piano in my life, but thought I would give it a try. Found this app and it worked perfectly! I am now playing with a great TUNED piano. Saved me hundreds

Really handy for my piano, and saved me from calling the Tuner. The app is fast, and intuitive to use. The range is impressive. And I will try it with violin next. Nice touch with the dark theme mode.
