Must be just lovely for pets at home or is it outside of the frequencies that cats can hear (up to 79 kHz)?

Also this thread is filled with people complaining about bluetooth spying capabilities and now you post an app with bluetooth always on AND microphone always listening?

Thanks for asking. I'm the founder of NOVID. Our app has a pet mode if your pet does not like it. This doesn't seem to have been a problem. The microphone is also not always listening. It turns on for 2 seconds when needed. The complete app source code has been given to a university security research team for review, and they will see that the microphone is used only for its intended purpose: to process ultrasonic frequencies.

Out of curiosity, why not make the app source-available?
