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.
