So I think we all know about foreflight and wingx pro but I found another app that has a lot of the functionality of foreflight and is free for military. Its called AeroVie and is iOS only. There's an iPad and iPhone app. Both work well. Unfortunately the app is missing some stuff like helo and TAC charts and is only CONUS right now but it's free and filing, briefing, activating, and closing through it is very intuitive. The app description says "free CFI subscription" but Bryan comp'd my account without any problem.
Also, if you haven't used NGA Aero in a while, they're working on making it better.
