What is Reddit's opinion of VTX Calculator?

From 3.5 billion Reddit comments

You might want to look at an android app called VTX Calculator, which helps optimize which channels people use while flying together. It has dip switch positions for maybe a dozen different transmitters. It's also on github if anyone wants to contribute. (I'm not the author, just a fan.)

Yeah it's stupidly easy to do because some manufacturers use black, and some use white for the switch position.

Btw for anyone interested in a neat android app, vtx calculator shows the dip switch positions for various models of vtx, and is really helpful for organizing several people into optimally-spaced frequencies. On the latest version it added an S for the switch position based on which vtx you use, to resolve the black/white confusion.
