Features & Capabilities

Precision Strobe Tuner is a general-purpose chromatic instrument tuner app featuring specialized temperament and piano-tuning tools. It blends a radial Spectrum Display with a classic Strobe Tuner and a Note Dial, delivering a clear, visual map of pitch and overtones. The ultra-responsive strobe, trusted by technicians, and the color-coded octave spectrum provide fast, intuitive tuning cues. The Fundamental Indicator aligns the target note on the dial, enabling both coarse adjustment and fine-tuning precision as you approach the desired pitch.

In addition to standard tuning, PST 2.0 includes a Programmable Temperament function with five user-definable banks for piano stretch curves, alternate temperaments, or unique guitar/string setups. It also offers Special Measurement Banks for inharmonicity characterization and piano-stretch estimation, allowing selective measurements of the Fundamental and second harmonic to generate smooth, repeatable curves. The app supports calibration demonstrations and a detailed manual at https://www.precisionstrobe.com, making it a powerful tool for musicians, technicians, and educators seeking precise tuning results.

User Reviews

Reviews consistently praise Precision Strobe Tuner for accuracy, ease of use, portability, and depth of features across multiple instruments, and view it as good value with regular updates. Common drawbacks focus on compatibility with older iOS versions and microphone-based operation in noisy environments, which can hinder live performance. Overall, it’s a powerful tool for studio work and serious tuning, with caveats for mobile reliability and real-world noise.
Pros
  • Very accurate strobe tuning across a wide range of instruments (pianos, organs, guitars, dulcimers, violins).
  • Easy to use with rich temperament and color information.
  • Portable and always accessible on iPhone, ideal for on-the-go tuning.
  • Comprehensive, professional-grade feature set (temperaments and instrument support).
  • Excellent value with frequent updates and strong performance for the price.
Cons
  • Crashes or won’t run on older iOS versions, leading to compatibility issues.
  • Microphone-based tuning is sensitive to ambient noise and often requires an external pickup, limiting live-use practicality.
  • Occasional UI quirks or instability (e.g., spinny display, octave selector locks).
Recent reviews
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

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

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