Very good Once it has been set up correctly, an excellent app. Pay attention to the units for empty arm. Excellent support.
Put trial in the name Expensive ... just use a spread sheet using free office software
Problem with calculations Will never add empty arm to moment figure. Always shows weight as right number and graph placement. So W&B is always way forward. Even tried to add another station to mimick empty a/c but it wouldn't take that number either. Would be pretty slick if it worked.
Not free Expensive. When you can use excel.
Bad text color Gray text on the cloudy sky background is very hard to read. Simple black text would fix that eye strain.
Very handy. Needs moving cg for fuel, fuel in lbs, ZFW, customizable labels for stations.
Support for arbitrary CG envelopes
Ability to clone profiles
Improved user interface
Better support for tablets
