What's New in IntonationPro

1.3.1

October 16, 2026

• Singer mode vibrato: IntonationPro finds the center of your vibrato. Since singers usually swing down from the note, a vibrato below the note is no longer marked flat. • Held notes and onsets are judged by the vibrato center too, so drift and settling time are right. • Note names corrected in every key: in G sharp minor the seventh degree showed as F sharp while G was sounding. • Pitch detection stays steady when open strings ring along. It could lock onto a much lower note before. • The manual and the intro cards explain how vibrato is judged.

Response from developer

Vielen Dank für die Rückmeldung — das tut uns leid. In Version 1.1.5 gab es bei manchen Geräten (besonders mit USB-Audio) einen Absturz beim Session-Start. Das ist behoben; bitte aktualisieren Sie auf den neuesten Build von 1.1.5 bzw. löschen und neu installieren. Wenn es danach noch abstürzt: kurze Mail an intonationpro@danielauner.com mit Gerät und iOS-Version — wir helfen sofort.
