Microphone Permission

IMPORTANT: When you launch UniTuner Pro for the first time, you’ll be prompted to allow the app to access your microphone. This permission is essential for the app to function properly. If you initially denied access, you can enable it later in your system settings. Go to the Settings & UniTuner Pro and enable the microphone. (see Figure 1).
The microphone is only used to detect pitch; no recordings are permanently stored or used outside the app!

Figure 1: Allow the app to access the microphone

Overview

One octave is divided into 12 semitones. Each semitone is further divided into 100 cents.

A reading of zero cents means the note is in tune. A negative reading indicates that the note is flat (too low), while a positive reading means the note is sharp (too high).

IMPORTANT: Make sure that the tone you want to tune falls within the measuring range. If it doesn’t, the tuner might register an overtone instead. Always verify that the measuring range includes the note you wish to measure! (see Measuring Range)

You can quickly access the app settings by tapping the designated user interface element.

Figure 2: Overview

1 - Measuring Range

Tap the measuring range symbol (1) to open the measuring range menu (see Fig. 3).

By default, the measuring range is set from C1 to C6 to cover most instruments.

Change Response Time

Different measuring ranges may affect the tuner's response time.

IMPORTANT: Make sure the tone you’re tuning falls within the selected measuring range. Otherwise, the tuner might display an overtone instead. Always verify that the measuring range covers the note you intend to measure!

2 - Concert Pitch

Concert pitch refers to the frequency assigned to the note A4, which is typically set at 440 Hz.

In some cases, you might want to choose a different concert pitch. For instance, when tuning an old piano that requires a lower tension, a different pitch may be preferable.

Alternatively, you may adjust the concert pitch to slightly lower or raise the frequencies of the notes you play to suit specific musical needs.

IMPORTANT: When using the sine wave, your device’s speakers may not be able to reproduce frequencies below 200 Hz.

2 - Frequency button

Swipe to select a note.

Tap to set a specific frequency.

3 - Cents button

This button appears when the current frequency deviates from the tuned pitch of the note.

Press it to reset the deviation to 0 (tune the note).

Press the button to activate the playback function. The button will flash to indicate that the app is waiting for you to play a note.

Once the app detects a frequency, it will begin playing it back.

Figure 8: Tone generator controller

The standard tuning system in Western music is known as “12 Tone Equal Temperament” (12-TET). In 12-TET, the notes in an octave are evenly spaced, resulting in equal intervals in any key. However, these intervals are not as "pure" as those found in nature.

“Just Intonation” provides "pure" intervals relative to a chosen root note, but as you move further from the root, the intervals can sound increasingly dissonant.

Other temperament systems attempt to strike a balance between “Equal Temperament” and “Just Intonation”.

Tip: If you are using an open tuning, set the temperament's root to the open tuning’s root note and choose “Just Intonation”. Give it a try!
