About this app

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.

This new version never expires. 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.
* File read and write. Save and restore audio files in .MP3 or .WAV format
* Rename or delete .MP3 or .WAV files
* Max file length selectable from 1 to 99 minutes
* Screen is kept on during recording and playback

Ratings and reviews

Succinct. Great visual of intonation. I love that you can specify the key so it's visually easier to tell where you are relative to the key. Not sure if this would be an improvement but a thought to consider; possibly placing the left column note names in the right column as well to tell a bit quicker where you landed initially without having to look over to the left and back to the right when the notes are moving a bit quicker than whole tones.

What a brilliant app. Extremely helpful for self violin tutors. Works like a tutor is sitting right infront of you. It would help even more if I could listen all the scales and then play in tandem.

Great for string players to "see" where your pitch accuracy is in real time. Update 3 years on and still using this every time I practice. This one is a keeper.
