INTUNATOR - Improve your Intonation by Ear!
It's ingenious and simple!

The INTUNATOR is an innovative, new training aid to assist in the development of correct intonation for all wind and string instruments. The App recognizes the note being played and plays it back with the correct intonation through the user's headphones. While you are practicing, you will intuitively match the note you are playing to the note you are hearing. You are literally training your intonation by ear as you play. INTUNATOR always gives you the right note, whether it's a single note or an entire piece of music!

Simply connect your headphones, start INTUNATOR and play what you'd like on your instrument.

It's ingenious!


Pitch Detection:
INTUNATOR immediately and accurately recognizes the note played over a range of nearly 7 octaves.

Audio Output:
The recognized pitch is corrected according to the tempered scale and played back as long as desired into the headphones being worn by the user. Three specially developed sounds developed specifically for this purpose, as well as a volume control allow the user to create the optimal balance between their own instrument and the tone being played back by the INTUNATOR.

Visual Aids:
The note names are shown on the Display. An easy to understand graphic supports the user's intonation control.

The note names are shown in their transposed form.

User's Assistent:
An automatic User's Assistant is there to insure a quick and easy application of the App for the user from day one.

Individual Settings:
There are various possible settings: Choice of Instrument, Transposition, Concert Pitch, Volume of Background Noise, Display of Frequency and Deviations in Cents, Notation Preferences in either sharp or flat, Audio Output Sound, and the Pitch Detection Number, which is determined by the instrument being used.

The INTUNATOR can be used as a reliable tuner over a range of nearly 7 octaves.

You can play what you'd like on your instrument. The INTUNATOR will always accompany you with the "right note". Improve your intonation by matching the sound you hear in your headphones to the one you are playing on your instrument.

The app's visual display will help you with this. Over time, you should slowly try to wean yourself off of the visual aid and use your ears more and more to help you improve your intonation. Learn the intonation quirks of your instrument! Correct your intonation intuitively. Enjoy exerting control over your instrument.

Let the INTUNATOR help you to learn how to improve intonation on your instrument! Our method teaches all musicians how to improve their intonation in the most obvious way: By using their ears! Practice independently and without outside help.

What’s New

Version 1.8

This app has been updated by Apple to use the latest Apple signing certificate.

The sound output has been debugged! INTUNATOR runs flawlessly on all devices with this update. Additionally, the control tone can now be heard via bluetooth from IOS 10.3, which the stringed instruments will find particularly pleasing. (Due to the transmission technology, however, this will be at a much slower speed). The fastest and best sound output is still achieved via cable connection. We welcome any feedback via the support contact in the APP or at www.intunator.com. We generally respond to questions and problems within a few hours. We also welcome positive reviews in the App Store and on Youtube. Best regards, Markus Rombach

Excellent App!

This is an incredible app! I use this app to help those students that struggle with the concept of in tune playing. Beginners can use the visual aspect to learn what in tune playing sounds like.

I also create assignments for my private lesson students and it changed the way I teach intonation.

Excellent intonation training

Works very well, I’m using it with cello. There is some delay, so it’s best for slower tempo practice. Wish they would move the “notation preference for sharps/flats” to the main screen because I adjust that differently for each key.

Garbage. I want my money back.

This app is terrible. I have it set to the correct instrument. It’s shows me playing in tune. Even displays the correct note I’m playing. But in my headphones it plays a note a half-step away from where I am.
