User Reviews

The app was once a capable real-time spectrum analyzer, with useful features and believable accuracy. However, it has become unreliable and largely nonfunctional due to crashes, lack of updates, compatibility problems with newer iOS versions, and unresponsive support. Many users report inaccurate measurements and broken visuals, leading to widespread dissatisfaction and refunds. The core strengths are now eclipsed by maintenance neglect and frustrated users seeking alternatives.

Pros

Historically useful for spectrum analysis and tuning when the app functioned.
Provided real-time spectrum visualization (FFT) during working periods.
The free version offered meaningful RTA capabilities and was appreciated before updates.

Cons

Frequent crashes and overall non-functionality after updates.
Abandoned/unsupported by developers; not updated for years and incompatible with newer iOS versions/devices.
Poor or no developer support (unresponsive inquiries) and lack of in-app help or documentation.
Unreliable measurements (frequencies not identified correctly; FFT issues) and general accuracy problems.
Trial limits hide most features, making evaluation difficult.

Recent reviews

Perfect RTA for working out any audio/studio to mix/EQ/stage for the best quality of sound. It’s free, no ads besides a built-in popup every now and then. Very customizable and accurate readings based on multiple FFT size choices
