## What is IntonationPro?

Play in tune – and see it happen. IntonationPro listens while you practice and shows every note as a smooth, color-coded curve: green when you are in tune, orange or red when you drift. You see instantly whether you are sharp or flat, and by how many cents.

Made by Viennese violinist and conductor Daniel Auner for everyone who plays a string or wind instrument or sings – and wants to hear and see clean intonation.

NEW IN 1.3
• Singer mode – train your voice: a reference tone to sing back, held notes, clean onsets and your vocal range
• Key recognition (iOS 27): IntonationPro recognizes the key from your first phrases and suggests it – analyzed entirely on your device
• Siri & Shortcuts: say “Start a practice session in IntonationPro” or put it on the Action button
• Larger views on iPad for progress, settings and sharing

TRAIN YOUR VOICE
• Singer mode: a clear view without keys and tunings – just your voice and the curve
• Reference tone: hear your starting note, then sing it back
• Held notes: how steady you hold a note, and whether your voice sinks or rises
• Onsets: do you hit the note right away or scoop into it from below or above?
• Vibrato done right: IntonationPro finds the center of your vibrato and knows singers usually swing down from the note, not above it – so your vibrato is not marked flat
• Your vocal range per session and over days

REAL-TIME FEEDBACK
• Precise pitch detection with low latency
• A flowing curve that makes vibrato, glissandi and intonation drift visible
• Note name, deviation in cents and scale degree at a glance
• Golden sparkles and a smiley when you play a beautiful vibrato in tune (optional)
• A hint when a passage is too fast for the detector

MUSICAL, NOT JUST TECHNICAL
• All 24 major and minor keys – natural, harmonic and melodic minor
• Three tuning systems: equal temperament, just intonation and Pythagorean
• Concert pitch from 415 Hz (Baroque) to 446 Hz
• Three tolerance levels: strict, standard and relaxed

AFTER EVERY SESSION

Von mir gibt es für diese App sechs von fünf Sternen.
Ob Musiker:in oder Sänger:in, Intonationsübungen machen mit dieser App einfach nur Spaß und die Auswertung ist sehr hilfreich, um seine Erfolge zu messen.
Fünf Minuten kostenlose Testzeit am Tag reichen völlig aus, um von dieser App überzeugt zu sein. 
Ich hatte ein technisches Problem, aber der freundliche Support hat mir sofort geholfen.

### 1/5 — App stürtzt sofort ab

*2026-09-06*

Leider funktioniert sie nicht.

**Developer response:** 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.

## Version history (last 5 releases)

### 1.3.1 — 2026-10-16

• 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.

### 1.3 — 2026-09-21

• Singer mode: train your voice with a reference tone, held notes, clean onsets and your vocal range – vibrato is judged by its center and upper edge.
• Key recognition (iOS 27): IntonationPro now recognizes the key from your first phrases and suggests it. The analysis runs entirely on your device.
• Siri & Shortcuts: start a practice session or open your progress by voice, from Spotlight or with the Action button.
• iPad: progress, settings, sharing and key selection now open as large pages.
• Help: a detailed user manual and quick explainer cards in Settings › Help.
• Built for iOS 27.
