What's New in iPegs

4.3.0

September 2, 2026

A few new features! * A new screen that shows you how your temperament compares to just intonation (thanks Jeroen) * You can now play multiple tones at the same time if you like (enable it in Settings, and hat tip to Jeff for the suggestion) * Cleaned up the bottom bar to make more room on smaller devices (hope it helps you, Christa) * Otherwise, the usual: fixed some bugs while hopefully not introducing others. Let me know if you have ideas or requests!

Great app!

The developer has added so many new options and features! Love the new interface — efficient and easy-to-use — and now it even has its own strobe-like listening. The temperament interface is by far the best one around, including the ability to actually tune all the chromatic notes in a meantone temperament!

Crashes in iOS 9

After I updated to iOS 9 on an iPhone 6, this app fails to open. It hangs and crashes.

Response from developer

After many years, I finally got around to updating the app. Please give the newest version a try! It's been completely rewritten and expanded.

Great with VoiceOver

Title says it all.

Wonderful Tuning App

This app is easy to use and extremely accessible with the Voiceover screen-reader. It's great for tuning by ear, which is what I do, and I'm glad I won't have to carry around a brace of tuning forks anymore. :)
