Intonia is a Pitch Recorder. It's software intended to help string players visualize intonation. It combines the capabilities of an electronic tuner and a digital recorder. It keeps a memory of what it has heard, and displays pitch on a scrolling graph. You can specify what temperament to use: Equal, Just, or Pythagorean.
While it is recording, the display scrolls continuously. Your pitch is displayed as the height of the trace. If you're playing in tune the trace is white, but if you're sharp relative to your chosen scale and temperament, the trace is colored red. If you're flat, the trace is blue.
The free version is limited to one minute of sound storage, A=440, equal temperament.
An in-app purchase will upgrade to the Pro version. The Pro version includes the following:
* 'A' frequency settable between 400 and 499 Hz
* Choice of Equal, Pythagorean, or Just intonation.
* Save and restore audio files
* Rename or delete audio files
* Import and export audio files from/to iCloud
* Up to 60 minutes of sound storage
* Screen is kept on during recording and playback
* Playback and record in background mode while the screen is not showing
Here are some things you can do with Intonia:
* Play a fast passage, and see which notes were out of tune.
* See intonation in just, Pythagorean, or equal temperament.
* Tune your instrument.
* Use as a digital recorder to hear yourself play.
* Get instant feedback.
* Visualize articulations, slides, shifts, vibrato, etc.

Ratings and Reviews
This app not only showed me why my playing didn’t sound so great, but also how terribly uneven my vibrato was. After using this for about six months, my playing is much more in tune, and my vibrato is coming along.
As a calligraphic artist, I especially enjoy the way the internation line looks like a brush stroke. When it’s in tune and the vibrato is steady, it’s a work of art. When it’s out of tune and you have a lot of bow noise and your finger isn’t quite contacting the fingerboard, it looks as terrible as it sounds!
Love it. It is truly an inspired app.
I used the Mac desktop version of intonia years ago to work on my intonation (on fiddle). I just got the newly released iPhone version, which is even better than I remember the desktop version being because it allows you to import music files (even from cloud servers, like Google Drive). This is a fantastic feature for transcribing recordings because you can see all the note pitches in real time as the music plays.
Exactly what I needed
Beth Blackerby of violinlab.com recommended this app as a tool for checking intonation. It has been very useful in helping me to learn correct finger placement and I definitely feel that it has made a big difference in helping me to more quickly develop muscle memory on the fingerboard.
