    This app generates nice spectrograms of the mic input; however, the software is lacking some basic and obvious features. First, the app does not save user settings from a previous use, such as the preferred color scheme. Second, there are no zoom options

    Why, why, why is there no zoom feature? And why timer doesn't resolve sub-seconds; just seconds only? Dev: Presume app is used on device only.

    Very Nice.
    I have been able to use this to identify and isolate a number of sounds. Very simple to use. Looking forward to find new uses for this.
