SpectrumView

Using iOS 16.6 on an iPhoneXs, was able to transfer a sound recording from my in-phone files folder to the SpectrumView app. Initially, I could play the file and view the spectrogram. I payed $1.99 just to be able to zoom in on the spectrogram (a ridiculous price for a very basic functionality!) to focus in on specific sounds. Following my attempt to zoom, the app crashed. Now every time I attempt to view the file, the app crashes. Perhaps this is by design as you have to pay $0.99 just to access files from iTunes or SoundCloud (which I also purchased). This app seems useful if only one could use it!

The visuals are both practical and cool to watch. I would love to see the fonts a little larger and much more readable when trying to analyze a peak frequency. It’s possible and freezing and expanding makes it much easier but the font and locating it needs work. Aside from that one gripe I do really like this app.

Hello! I’ve been using your app now for a month and it’s working very well up until now. When I Download the app it immediately popped in and update in the application which I’ve never seen before when you download an app from the App Store it should already be in the latest version correct? It’s not the latest version important update and if I don’t do the update the app works for two seconds and then it doesn’t work at all literally blank when I’m trying to record!!! I know it’s nothing else it should be picking up the motion of the fan in the room and it won’t even do that.
