Love it easy to use and can make 5 profiles. But the app lacks G7 BC, Atmospheric pressure, and humidity input

Does exactly what it should. Simple to use. Calcs seem accurate and graphs and tables are nice and clear and easy to use. A super useful and well put together app.

This is exactly what I was looking for. I log my favorite loads into a private database I wrote for myself. But this app delivers the calculations. It is very accurate as I have proven over and again on the range and out in the woods.
