KeyTuner 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

Helped me tune up a 170 year old piano to concert pitch
I had a project to bring a parlour grand piano that was very out of tune (consistently at least two semitones flat) back to concert pitch.
It took several iterations to get there, but it is now at concert pitch and sounds fantastic.
Many thanks to this app.
No good for brass
No good for Eb brass

Good apart from one small detail.
I downloaded this and was impressed with how well it picked up the notes on my replica historic instrument. Many other apps fail to do this anywhere near as well. The only thing letting it down is the lack of different temperaments available. Playing baroque and classical music I use a modified mean tone and to use this app I need to calculate the deviation from equal temperament and tune each note sharp or flat by the required amount.
( KeyTuner ) 🎶 ⭐️⭐️⭐️⭐️⭐️
I’ve been a musician for many years, this the best tuner I have had the pleasure to use. It’s very useful for intonation check on guitar, and wonderful for harmonic tuning. There is no doubt you can trust this tuner to tune a piano. Just like to say, a Big ThankYou to the developer of this free application KeyTuner! In my personal opinion, the best tuner on the App Store.
The best music app I’ve used.
Ten years of using different tuning apps - this beats them all. A very accurate tuner. The drone function is perfect for singing. Wish I’d found it sooner. Get it.
Wow I learnt a skill !
This is fine to do pianos with , surprisingly !
Great for a Kalimba!
Many ways to use this, I use it to tune my Kalimbas. It’s the best free one I’ve found. I love that you can use the frequency to get it exactly right, or the standard graphics with letters and a needle.
Excellent. Exactly what is needed.
A truly great app. Simple to use and covers different instruments.
