I've looked and there's almost nothing useful for soldiers in the app store... The obvious military apps: Military manuals - most of these are available in pdf format, with lots of charts and images. The only way I've found to access these is to convert the format to html, host on a website, load in safari, save using instapaper, then read at my leisure. None of the current eBook software can handle these documents (Bookshelf has no searching and won't let you zoom in on pictures, while stanza, books, and ereader won't support images and charts) Military maps - I want a simple topographical map viewer that lets me input or find grid coordinates in MGRS format. Also, find the distance and azimuth (in degrees or mils) between two points. And, I'd like to be able to plot routes with waypoints and show that on the map, and show the data in some kind of table (waypoint 1A, grid AB12345678, direction 186degrees, distance 4220m) and set important grid locations/phaselines (Rally Points, Casualty Collection Points, etc.). Sadly, Google Maps and Google Earth don't support MGRS, topographical maps, or any of the rest. Nothing else does either, so far as I can tell. Translation software that can be used offline - Arabic, Pashto, Dari. Everything I've seen so far requires an internet connection, and nothing seems to support Pashto or Dari. Flashcard viewer - There's several of these programs out there, so I'll need to find one that works. I have cards on common radio formats, range estimation data, demolitions calculations, bridge classification, CAS data, etc. etc. Checklists - I'm sure there is lots of software that does checklists for PCCs (Pre-Combat Checks), vehicle/ruck loadplans, etc.
