Precision Strobe Tuner
$3.67About Precision Strobe Tuner
The Precision Strobe Tuner main screen features are the Spectrum Display, the Note Dial and the Strobe Display.
The central Spectrum Display shows the input spectrum wrapped around the Display, with each Octave drawn in a separate color. The Note Dial is marked like a clock with the twelve notes of the Scale. All overtones of the input are shown as peaks in the Spectrum Display pointing towards their corresponding Notes. The Fundamental Indicator Tic on the Spectrum Display shows the Note of the Fundamental along the Note Dial, with the color designating the Octave. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note Indicator.
As the input approaches the desired Note, a Two Group pinwheel pattern becomes visible rotating in the Strobe Display. Fine tuning is accomplished by adjusting to stop rotation. The Strobe Display responds instantaneously to changes in pitch and is extremely sensitive. The outside Strobe Display works just like a classic rotating disk strobe tuner. The Two Group pattern rotates CCW when the input is flat, and CW when sharp. When the rotation is stopped, the note is in tune.
One screenshot shows the display tuning a Guitar Low E string. The Fundamental appears as an Orange peak in the Spectrum Display. This string rings bright, so the overtones are also dominant in the Display. Several other screenshots show the display for other Guitar Strings.
Another screenshot shows the display for an E 440 Tuning Fork with the Calibration Dial enabled and set. This Fork is 1.3 cent Flat.
The PST also includes a Programable Temperament Function with 5 user definable banks. The final screenshot shows an example of a Temperament Bank setup to a typical Piano Stretch Curve. This can also be used for tuning alternate temperaments, pedal steel guitar setups, or special guitar intonation systems.
In addition, there are several Special Measurement Banks used for String Inharmonicity characterization and Piano Stretch Curve Calculation. Individual strings are characterized by measuring the Fundamental and 2nd Harmonic separately. By careful selection of a few representative measurement points, a reasonable smooth fit Piano Stretch Curve can be generated. Any number of measurements up to C7 can be used.

Works very well.in pro version has fender Rhodes piano stretch tuning inbuilt.easy to use and calibrate. Can see if flat or sharp by frequency pointed at if strobe is fast which is handy.well worth buying Small problem when a default setting is used when tablet screen saver comes on. When tablet touched app looses the custom setting and you have to reload the custom setting again. Perfect software apart from that.

Running this on a G'zOne Commando 4g. Only app I could find that supports the octave stretching needed for piano tuning. The inharmonicity measure mode took me awhile to figure out how to both tune the piano above and below the temperament octave and calibrate the curve but after much trial and error, I was able to make it work. Very happy with the results so far. Recommend an external Mic to pick up the bass notes.

If you would like to attempt to tune a piano with an Android device, then this is the app to use. Inharmonicity calibrations are made by measurements of the fundamental tone and the 2nd partial. The app allows saving 5 custom stretch tables for individual instruments. The "strobe" is easy to read, and appears to be a good combination of sensitivity and averaging. The degree of accuracy may depend on your device, so fortunately a demo version is available. Considering what a dedicated tuning instrument with custom software of this caliber would cost, $5 is a steal. Note: On my phone, the app would not defeat the system display sleep, so it was necessary to set it to 30 minutes so as not to be interrupted during tuning.

AS a retired piano tuner of 30 years experience, I can recommend this app completely. It identifies note names, it is easy to see where the pointers are on the dial, and it has two built-in tuning curves. I t also lets you save a tuning profile for a specific piano. Robert Walshe, Ruidoso, NM
