Precision Strobe Tuner Lite 1.62

A General Purpose Chromatic Musical Instrument Tuner App with special Piano Tuning Functions.

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.

The first screen shot 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.

The second 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 third screenshot shows the Input Signal Scope/Spectrum Display Page.

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.

Last year I sent the fee that turns off the frustration time waster so I could play with this.
This ap made my iPad get hot and drained the battery real fast. Next, I found that using this didn’t work better than a cheap tuner and in fact what you discover is that you waste all your time finding out that you can’t make the custom extra features work. My I pad has only 16 gig and I needed space, the app is fun to play with but in a practical sense, it’s useless. Took the app off my iPad thinking if I wanted to play with it someday I’d load it in again. That’s fine except the “premium” I paid doesn’t stay with the app, you have to buy it again. Again, the ONLY thing the $5 did was remove the time waster it did NOT make the custom functions work. I think the seller believes that lots of sellers abuse people so he does too.
I put the app back in today to compare it to the accuracy of my Peterson StroboPlus HD. I can actually tune with the Peterson. Granted, the Peterson is the real deal but it cost a lot too. When this app indicated a sharp pitch the Peterson indicated the same pitch as flat - whatever that means. One star because WE are paying him to do the testing and because nothings changed with the features. However, same I have the same iPad and it didn’t heat up nor the battery discharge.

Great

I bought this about 7 years ago. It was pretty good, then they made improvements. Now it’s great. I started tuning the piano at my gig. It was always going out. People were impressed on how well app work they started asking me to tune their pianos. Now I tune pianos on the side, this app made me money. This is by far the best app I’ve ever bought. It uses your battery life real fast so I make sure I plug it in.

Awful

I do not recommend this app. Every time I launch it goes through a long involved procedure of teaching you how to use it which would've been nice the first time but then it just does it every time you launch it so it's pretty useless
