Description

Precision Strobe Tuner 1.92
A General Purpose Chromatic Musical Instrument Tuner App with special Temperament and Piano Tuning Functions.
The PST combines a radial Spectrum Display with a classic Strobe Tuner and Note Dial for an ultimate visualization of pitch and tone. The Strobe Display is highly sensitive with response speed that is practically instantaneous and has long been the preferred tool for piano tuners and instrument technicians.
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 previews show a general strobe display demonstration, an example of using the calibration function to measure the accuracy of a tuning fork and an example of guitar string tuning.
The first 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.
The second screenshot shows the display for an E 440 Tuning Fork with the Calibration Dial enabled and adjusted. This Fork is 2.9 cent Flat.
The PST also includes a Programmable Temperament Function with 5 user definable banks. The third screenshot shows an example of a Temperament Bank set up 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 Estimation. Individual strings can be 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 can be used.
The final screenshot shows the Input Signal Scope/Spectrum Display Page.

Precision Strobe Tuner Reviews

Unusable in 2024

Tez925 on

United States

Honestly, I don’t understand all the positive reviews. This tuner is borderline unusable, maybe it’s due to the updates stopping ages ago, maybe it’s due to the microphone being so much different on iPhone 15, but this tuner cannot be dialed in, no matter what noise filters are on. God forbid you have central air going in the next room, it won’t be able to differentiate its note vs that of the guitar sitting 6 inches away. Only time I’ve ever felt legitimately ripped off on the App Store. Update the app or retire it

Love it!

Finally able to own an actual strobe tuner, that does exactly what it's supposed to do. No complaints here.

Great tuner

The tuner is very easy to use and it provides quite a bit of sophisticated, additional information related to color and temperament.

Love this app

I have the Peterson professional version tuner. This app competes with it.

Annoying display

Accurate app, but the spinning display is very annoying

Love this app

It's a great comprehensive app for strobe tuner. I have professional piano tuning software, but this is still extremely useful in many circumstances.

Very Good App

rcwaldhorn on

United States

I have been an aural tuner for over 30 years. But, as my ears aged, I needed help with the higher partials and about the two upper octaves on the piano. This app is very useful and is easy to use. I have also used the Android version with good results. Recommended. Robert C, Walshe

Excellent and Accurate Tuner!

Much Irrated on

United States

I use this a lot, and it’s very convenient since it’s on my iPhone. It is always with me, not in my guitar case. I love the Accuracy and simplicity! No problem until writing this review. It is making me make up a nickname!

Perfect tuning app

Red Feather Flutes on

United States

I constantly use this app to tune Native American Style flutes. A very big advantage is being able to see the harmonics of a note which shows me where slight adjustments need to be made. There are so many features available for very fine tuning. I would rate the calibration feature a “++” allowing for perfect environmental tuning. Hands down one of the best apps available for instrument making.

A ‘must have’ for piano!!

I can keep my grand in tune all year long! 🌞❄️
