Software Description

Plug in and tune your electric and acoustic guitars quickly and easily with 1/10th cent accuracy. (External mic required for iPod touch.)


  • Exclusive strobe display allows you to achieve an unmatched level of accuracy.
  • Note/Octave window displays the correct note and octave for the note being tuned.
  • Cents display allows you to see how far out of tune your note is in cent values.
  • Glowing flat/sharp indicators assist when tuning a note very far from the target position and it is difficult to gauge which direction the strobe is moving.
  • Noise filter: Use the noise filter when utilizing an external mic or clip-on tuning device to help reduce the effect of extraneous environmental noise during tuning.
  • Input boost: The input boost will raise all input frequencies by +24dB.
  • Calibration mode: iStroboSoft can be calibrated to an external source guaranteeing 1/10th cent accuracy.
  • Drop/Capo mode: iStroboSoft will auto-transpose notes up or down to one full octave.
  • Full screen mode permits the strobe display to be maximized on screen to allow better viewing from a distance.
  • Adjustable Concert A: Change the Concert A reference of the tuner to accommodate tuning to a fixed instrument, such as a piano, or tune instruments that do not utilize the typical Western A440 reference.

Changes in v1.40.00

  • Improved note detection code for better low note tracking due to iOS device filtering.
  • Added: Auto or manual note select. Can toggle between auto and manual note select (just touch the "auto/man" label).
  • Added: Display options. Can toggle to show: cents, Hz, MIDI note.
  • Option to not show tenths of cents (in settings, "show whole cents").
  • Flat and sharp lights have been changed so there are almost invisible until activated.
  • Added: Can now change Concert A and Drop/Capo from the main screen (touch and drag on value).
  • Improvements for retina display. Newer high-resolution graphics now available.
  • New look/feel by changing the case color. When "black" is selected, it goes back to the original "classic" look.
