User Reviews
Pros
- Professional-grade measurement with calibrated, trusted results.
- Cross-device subscription works across iPhone, iPad, and Mac (single license).
- Rich feature set for sound analysis (RTA, FFT, spectrogram, oscilloscope).
- Reliable performance and responsiveness—often praised as less buggy than alternatives.
- FFT-based analysis is helpful for debugging real-world audio issues (e.g., guitar pedal noise).
Cons
- Subscription gating hides key features (FFT, spectrogram) behind a recurring fee and marketing claims.
- Perceived high price and ongoing subscription costs after paying upfront, viewed as overpriced.
- Legacy licensing changes have disabled prior purchases or force new subscriptions (bait-and-switch perception).
- Lack of presets/save-and-load for different setups; data and configurations feel scattered/incoherent.
- Usability and documentation gaps (non-intuitive UI, weak manual, workflow friction, compatibility concerns with newer devices).

I have used this app for years, primarily as a teaching tool with my iPhone microphone. For some reason, it is no longer working. It will either start to record, then stop. Or it won’t work at all. The Faber SLM app seems to be working fine, so I’m not sure why the oscilloscope and FFT have stopped functioning. Very disappointing especially considering the price we pay for the subscription.

I've been kicking the tires to decide whether to subscribe. Right off the bat I was mystified by the apparent lack of the ability to store and retrieve various setups (after setting up a tool and its parameters) for making different measurements and/or setting up different displays. Since there is no manual, and the meager help file doesn't address this, as best as I could determine the software just retains the setup that exists when the program is quit. That limitation seems very odd. In general, a manual would help.
