Review summary

Overall, users find Audio Spectrum Analyzer useful and easy to use for basic audio analysis and FFT learning. Pros repeatedly cited include an intuitive interface, practical analysis capabilities, affordable price, and accurate peak detection at times. However, multiple reviews flag slow updates and responsiveness, occasional bugs with zoom and display, and mixed views on value versus free apps. Common requests include freeze/snapshot/export, manual peak markers, and improved zoom control. In short: solid beginner/tool with feature gaps and performance reliability issues.

Pros

Easy to use / intuitive interface
Useful and versatile tool for audio analysis / FFT
Affordable / good value
Accurate peak markers / frequency detection (e.g., testing with known tones)

Cons

Slow update rate / slow sampling
Bugs and reliability issues (zoom failures, resume/display glitches)
Value concerns: overpriced / not worth paying
Missing features like freeze/snapshot/export and improved zoom/marker controls

2018-02-18	Pi*****	Happy with this app. Frequency markers on peaks very handy. Checked against 500 and 600 Hz tones on WWV and both were within 0.1 Hz. Recommended.

2017-04-15	Ph*****	Does exactly what it says on the box. Sometimes buggy (at least on iOS9). Zooming sometimes doesn't work. Resuming the app after switching to something else makes it not display frequency data. Not perfect, but more than acceptable.
