It is important to first select the correct instrument from the menu.

With the correct instrument selected, the current tuning is presented on screen ("Default" on the left images). If there are multiple tunings for the selected instrument, a left and right arrow appears next to the tuning name where the tuning can be selected by tapping the arrows.

This is how to use it:
  1) Make sure the correct instrument and tuning is selected.
  2) Start plucking/bowing any single string.
  3) The companion will show how much away from the accurate tone every string is. Since you know which string you are plucking/bowing, you can tighten/loosen it until that string on screen shows correct tuning.
  4) Colors showing proximity of tone from string:
    - Red: string is less than 100 cents* wrong.
    - Yellow: string is less than 50 cents wrong.
    - Light Green: string is less than 15 cents wrong.
    - Green: string is less than 7 cents wrong (when 7 cents or less wrong, the center part as well as the opposite side also turns green).
    * 100 cents is the distance between two adjacent diatonic semitones (in equal temperament).
  5) Text above or below each string means:
    - Above: Text above a string means the string is too tight and needs to be loosened.
    - Below: Text below a string means the string is too loose and needs to be tightened.

  6) When you are happy with the first string, start over from 2) for the next string.

The frequency graph can be good if you have a problem with a certain environment or instrument.
If the graph does not show distinct peaks when you play your instruments, you might be in an environment not suited to identify the tones.

The singing range finder presents the range(s) of the selected voice as well as the ranges of all related voices.

When a tone is identified, a star is presented in each row where the tone is within the range of that voice (except for the top-most voice where the name of the tone is presented.

Use the singing range finder to learn more about the extents of your vocal range and in what voice(s) you can sing.

The identified tone, octave, accuracy, actual frequency and target frequency is presented.

The accuracy (in cents*) from the identified tone to the closest correct tone.

The actual frequency shows the frequency that was identified while the target frequency shows the exact frequency of the closest correct tone.

Since inTone Pro supports different temperaments (configurable in the menu by tapping the name of the currently selected temperament).
Equal temperament is the default temperament and the most commonly used temperament in modern music.
Equal temperament is a middle way where it is possible to freely change key of a fixed positions instrument like piano or guitar. If a piano is tuned in any of the other temperaments (i.e. not equal temperament), it is not suitable to play in any key since some keys will contain very dissonant intervals.
Because of this, inTone Pro will actually "re-tune" the instrument when the key is changed so that temperaments other than equal temperament show correct pitch/frequency for each tone for the selected key. The same goes for changing the frequency of the A4 tone (default 440Hz).
The best recommendation if you are not aware of the impact of different temperaments is to use Equal temperament!

* 100 cents is the distance between two adjecent diatonic semitones (in equal temperament).

Note: Transposing instruments − there is a setting (found in the cog-wheel setting in the menu) where an offset can be applied to the identified tones. If an offset is defined, the actually identified tone and frequency will be displayed enclosed in parentesis above the identifed tone (i.e. above the large A2 in the image on the left). All other information of this companions (i.e. all fields shown in the image on the left) and ALL other companions will present the offset tone and frequency.

The identified tone, octave and accuracy is presented.

The accuracy in cents (for more information about cents see above) from the identified tone to the closest correct tone is presented both as text but also as a traditional tuning meter where vertical means correct (0 cents), left means that the tone is too low and right means that the tone is too high.

The Flowing note sheet companion shows a history of the identified notes during the last ten seconds. The note value is defined by the time signature (and not length of played tones). It presents identified notes at the time when they were identified.

The Note sheet scale trainer will present the positions of tones in the selected scale on the note sheet and presents identified tones in green color if part of the scale (and in red color if not part of the scale).

The basic fingerboard companion presents all positions of the identified tone on the fingerboard as well as all octaves above and below the played one. It is usable to learn about the positions of your instrument and helps you to find the best positions (and strings) to play for the piece you are studying.

The Fingerboard interval trainer will present the positions of identified tone on your fingerboard. The identified tone is presented with a large circle (brown for reference tone, green for correct new tone and red for wrong tone).

This is how to use it:
  1) Tap the cog-wheel to select which interval the companion should present.
  2) If you want to start at a specific tone, play that tone until it is visible on screen as a green circle.
  3) Tap the play button (triangle symbol = Play, rectangle symbol = Stop) to start playing the selected interval starting with the currently shown tone.
  4) Tones one interval higher or lower of the reference tone is shown as light green small circles.
  5) Identified tones matching the reference tone is shown as brown large circles.
  6) Identified tones NOT matching the reference tone or any of the interval tones is shown as red large circles.
  7) When you hit any of the interval tones (small green circles), that tone becomes the reference tone and the new intervals to that tone is presented.
  8) To start with a new reference tone, tap the Stop button (rectangle) to clear the reference tone.
  9) Then tap the Play button (triangle) to start with a new reference tone.

The Circle of fifths/Interval companion presents the current and previously identified tones in a circle of fifths as well as in a note sheet. It presents the name of identified interval as well as the interval size (in cents).

Please note: To make the circle of fifths companion more stable so that you have time to read the information, it requires two consecutive tones to be stable as the same tone/frequency to be "registered as tone" at all.
This means that if you are in a noisy environment where the other companions of inTone will move a lot between different tones, the circle of fifths companion might not show any tones at all. You need to play/sing tones extended (in time) so that inTone can identify them as stable tones.
