Rubbish
Doesn’t show a live graph. Sometimes doesn’t show a graph at the end either, just a bunch of difficult to read JSON. Doesn’t show any results while running. Only after it completes. Save your money and look elsewhere. Update: I am perfectly calm. I’m just disappointed in myself after spending money on this app and then being insulted by the developer. I wish I had read the other reviews first. I did, in fact, set the interval option. This app appears to be a minimal port of a free command line utility which, I might add, has a much more robust set of options and instructions in its man page. The only value added by this developer would be the graph, if it worked. At best, I can get it to show 1 to 3 data points before wiping the screen and starting over. At worst the graph doesn’t display and the screen is filled with JSON output. Very inconsistent. If I could give zero stars for the rating, I would.
