Where is the phasing calculator?

I bought it and was looking for cable harness/phasing calculator and cannot find it.

Nice collection, needs refinement

I like the thought behind the assembly of tools, the collection is great enough for legit RF and work. The app could benefit from a UI and usability review to improve idiosyncrasies.

App repeatedly crashes

The app looked like it would be useful, and installing went smoothly enough. Once in the app, it looked like upgrading to pro would be useful. But every time I tapped the Upgrade to pro version, the app Crashes. Guessing the developer doesn't want my money?

Many functions simply do not work.

I was hoping to get a good model to build antennas. Unfortunately the model seems to be incomplete. Would be nice if it worked.

Works minimally…

Most buttons don’t work. Some calculations are off by up to 17%. Relatively worthless. Idea is good but it doesn’t work. Wasted my money.

Resistors in parallel

Does the app do anything do anything? I can’t get it to do anything.

Colors

Background colors non adjustable no functional control?

Needs improvement

Just downloaded it. There are no formal instructions on how to use it. For a beginner, you have no idea where or how to begin.

Great resource!!!

This is an amazing resource and well worth it!

All in One Excellence

If you love to tinker and build antennas and other things this really is the best App out there. It’s quicker than going online and hunting for formulas. I like how you can select the output from Metric to Imperial. It was a real chore to always wonder what an antenna length was when now I have ALL of the answers. Thanks for a great app !!
