Great app

I really like this app. It is really easy to set up aircraft profiles and run calculations. The cloud syncing is also a great feature, which makes it easy to sync aircraft profiles between my iPad and iPhone as my primary and backup electronic flight bag. The app also includes useful features such as the ability to set up baggage compartment individual and combined limits, adjustable fuel burn order between different tanks, and variable fuel moment arms.

I bought this app to replace a different, aging weight and balance app that wasn't kept up to date by its makers. I shopped around and bought this app because the developer's website looks professional, other users gave it positive reviews, and it has received recent updates.

The only additional feature I wish this app had would be an error message if maximum landing weight (MLW) will be exceeded due to insufficient fuel burn. You can set a maximum landing weight if your aircraft has one, input an enroute fuel burn, and see the calculated landing weight. However--although the app warns you of any other type of error I can think of--no error message is generated if you will exceed MLW. I suggested this feature to the developers, and I received a reply within hours stating that they liked the idea and would look into it, so they seem very responsive.

Makes my job easier

Being a CFII and doing the occasional intro flight is common in my profession. And people don't always tell the receptionist that they are bringing two additional people with them on the flight. So having this tool to quickly punch in the numbers and get an accurate and easy to read display of whether the aircraft is within CG or not, is very helpful. I would recommend this to any full time pilot.
