Peterson Tuners has offered tuning solutions for over 65 years and is the only company specializing in hardware and software tuning products for all levels of musicians.

• NEW - 12 Temperaments with adjustable root control.

• NEW - Display all sharps note display.

• NEW - Assisted Low Note Detection (ALND) helps capture very low frequencies.

• Smooth, real-time 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.

• Tune in auto or manual mode.

• Toggle the display to show: cents, Hz, MIDI note value for the note being tuned.

• Glowing flat/sharp indicators assist when tuning a note very far from the target position.

• 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.

• 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.

• Full screen mode permits the strobe display to be maximized on screen to allow better viewing from a distance.

• Change strobe display colors to accommodate different lighting environments or set a preferred user color for those with limited color palette recognition.

iPod touch:

- 2nd and 3rd generation users will require an external microphone similar to a headset mic used with the iPhone.

- 4th generation users can utilize the built-in mic on their device.


- Users can use the built-in mic for tuning or connect direct via the headphone jack using an approved adaptor cable or interface.


This version is universal and will function on iPad 2nd Gen+

Optional adaptor cable for direct line-in access as well as mini capsule microphone available from Peterson.

Simply Amazing

I have a new Iphone 4 and bought it a few days before the update that made it compatible. Now that it works and I have tuned my guitar collection, all I can say is WOW. I have several different models of Korg tuners, and numerous clip on tuners, but until today after tuning with IStrobe they have never sounded so great. I believe it meets its claim on 1/10th of a cent accuracy, which for ten dollars is a total steal.

5/5 stars


I was very skeptical. I've read about strobe tuners and how they work, and it didn't seem like this could do anything like a strobe tuner in a sensible way. However, I use my iPhone as a tuner a lot, and I thought I would give this one a try even though it is so expensive, mainly because of the positive reviews. It works great! It snaps on to the note lightning fast and shows very repeatable results. I found that I could do more with it than I could with other tuners. I used it to tune my tom drums, and it is fast enough and accurate enough that I could see the effects of tiny adjustments on the drum lugs and I could get the fundamental note of each tom right on pitch to a nice set of intervals. My other tuners don't work with tom drums because the fundamental bends in pitch quickly and the overtones are irregular, but this tuner is fast enough and tracks accurately enough to do it. Neat tool!

5/5 stars

Better than my Boss.

Ive had this tuner for 5 minutes and it's already better than my 80 dollar Boss. This just made my iPhone priceless. No complaints about anything just please keep it updated and bug free!!
