Bat-Detection
Good App in combination with audio moth ultrasonic microphone. Makes the bat calls perfectly visible and gives the possibility to save the records for later analysis.
OUTSTANDING!! Laboratory quality spectrum analysis!
I am an Electronics and Optical Technologist and have used professional laboratory instrumentation for over 30 years and
this app brings true realtime audio spectral analysis with an optional embedded realtime spectral display in a picture-in-picture window on the main display. The quality and accuracy comes from very high-speed signal recording and analysis, and includes an ultrasonic audio transposing mode to make this app function like a professional instrument ( nevermind the convenience and portability of being able to carry a spectrum analyser in your shirt pocket or on your ipad! ) THANKYOU for the Bluetooth update!! (i’m using my new TinySA Ultra to scan RF today!!)
Outstanding app! KUDOS to Pawel!!

$20 for *this*?
This app is pretty amateurish, not even supporting Bluetooth headphones on iPhone. It's 2025. When was the last time you saw an app that could only output over wired headphones? I didn't realize that was even a possibility. It's like the developer stopped trying back around 2018, and never updated it further.
The app's readouts also mix dB (SPL) and dBFS freely, even though there is no way to get SPL without first calibrating the system. What's up with that?
The whole thing just feels very "beta version written by a student in their dorm room." This is the single most expensive single-purchase app I have ever encountered. I probably wouldn't bother to keep it even if it were free.

The latest version now includes support for Bluetooth headphones. I hope this enhances your experience with the app.
Counter surveillance uses
Anybody who’s the victim of any kind of surveillance abuse or voyeuristic abuse in general, can use this app to pick up on a nearly imperceptible frequency around 14,000 kHz. The untrained ear you wouldn’t be able to hear this frequency but it is the result of using wave generated surveillance systems such as the CTX 4000 or the national security agencies tempest program that uses subtle amounts of non-ionizing radiation directed at the building that the target is in to pick up on all the electronic and more importantly biometric information similar to what you get from the xavor1000 system.
Simply run the recording through a program like audacity or adobe audition and increase the decibel rate what’s you hone in on it with the apps spectrum analyzer.

No headphone monitoring support
I was keen to use this app with my Ultramic 384 USB mic and AirPods Pro for real-time repitched monitoring of bat calls, as described in the docs. However, the headphone monitoring crashes after less than a minute, and requires a reboot to resolve. The app author stated that Bluetooth headphones are not supported, blaming the issue on Apple having retired support for wired headphones. However, this was 7 years ago, which should give ample time to update the app. This means that real-time monitoring of USB mics is effectively not supported on present-day iOS devices.
