User Reviews

useful for identifying frequencies. would be great if there were settings to change bandwidth and export data to CSV

This app is simple, but really nice. Of course the better your mic is, the better it will work. I’m using an iPhone 16 which has a really good microphone, and it can pick up sound frequencies that I can’t even hear with my ears. It’s neat to see the real time sounds being printed on the spectrogram. I suppose if I were to want additional features, it would be the ability to record, and also maybe see a history of one minute or two of past sounds. Other than that, I love it and I feel it was worth $2.

Please add a save feature. Works perfect but there have been times where I have needed to compare sound levels I can't because if I close the app it erases everything.
