    1.0 out of 5 stars Shouldn’t it prompt you if device is incompatible?

    I wish I could use it it some way, but I guess I just donated to this developer, as the product does not work on my device, and I cannot find a way to “return” it.

    3.0 out of 5 stars OK program, but not outstanding. You could get freeware(s) which have similar funtionalities.
    Reviewed in the United States on February 7, 2016
    The program is not a freeware. So, I expected more options than what this offered.
    The options are:
    1) Sampling rate from 8K to 48K
    2) Setting of min/max frequency
    3) Manual scaling.
    4) Display in log frequency.
    5) Saving the graph as file.
    6) Peak detect/hold.

    The casual observation:
    1) The screen update is about 1Hz at 16K bins.
    The screen update is about 0.4 Hz at 48K bins.
    2) The color of graph cannot be changed.
    3) There are no averaging options such as (1/3, 1/6, etc octave smoothing).
    4) Originally, I could not get this program to work on Android phone. The issue was resolved
    via google search. The problem was Amazon signing issue which logged me out of the
    purchased program. I send request for resolution to the developer, I have not heard
    back from this issue.

    Overall, it is OK program, but there are many a freeware that does more than this program.
