True Strings is a tool for fast and accurate tuning of any string instrument.

  • circle Select a tuning that corresponds to your string instrument
  • circle Pluck a string on your instrument
  • circle Instant feedback tells you if the string is sharp, flat or in tune
  • circle Adjust the tension of the string on your instrument according to the indicators
  • circle Repeat this procedure with all the strings of your instrument

True Strings indicates tones that fall outside the tonal range of your instrument in order to avoid breaking strings while tuning.

True Strings uses a tuning editor with which you can define tunings with any number of strings tuned to any tone within an acceptable range.


Feature highlights

  • circleRange of tone detection A0 – C8
  • circleVery high precision of pitch measurement, about 0.1 cent resolution
  • circleA detected tone is measured in respect to perfect pitch in cents
  • circleDisplays a musical note closest to the measured frequency
  • circleSeveral display patterns for accidentals
  • circleTransposition possible for instruments with natural key other than C
  • circleAdjustable reference tone A4 in the range 400 – 480 Hz
  • circlePreset temperament collection available

Tuning states

    Pluck any string and interpret the instant visual feedback. The string that is closest in range of the measured tone is highlighted. The measured tone is always in one of the following three states
  • flat
  • sharp
  • in tune
Adjust the string tension of your instrument according to the visual indicators.

Guided tuning


Guided tuning assists in keeping the entire instrument in tune with the least amount of effort.
    Set the tuning options to “guided” and select either
  • ascending or
  • descending
as your preferred way to walk through all the strings on your instrument.

Toolbar


All important tuning configurations are readily available in the toolbar on the right side.

Tuning library


Use the preset library of tunings to match your own instrument. Modify a present tuning or create a new tuning if necessary.

The library provides tunings for common instrument such as Bass, Bass Guitar, Cello, Erhu, Guitar, Mandolin, Shamisen, Ukulele, Viola, Violin.

You may choose “other instrument” if you have an uncommon instrument, which is not in the library.

Menu actions

    Options available on each string are as follows:
  • Select tuning
  • Play arpeggio
  • Delete tuning
Note that a currently selected tuning cannot be removed.

Tuning parameters


Effortlessly change any of the tuning parameters
  • Reference tone A4
  • Temperament
  • Transposition
  • Display pattern for accidentals
  • In-tune condition

Temperament


Inspect the scale of the selected temperament.

Tuning editor


Limitless extension possibilities with the tuning editor. Define any number of strings tuned to any tone.

Swipe to change tone


Swipe to the left to lower the tone, or swipe to the right to raise the tone in half steps.

Sound level threshold


Keep the sound intensity of your instrument above the background noise.

The idea with a signal threshold is twofold. First, ensure a reliable measurement of the instrument’s pitch (a weak tone is easily mudded by background noise). Second, the app’s pitch detection only kicks in when the the signal is sufficiently strong, which increases battery life.
