What iPhone/iPad/Android apps does the Army need most?

As a Combat Engineer having spent most of my career down in the line platoons I think we could use the following Apps:

1. Demolitions Converter/ Calculator.  There is a lot of math to figure up when you talk about making timber cutting charges, cutting steel bars, or making explosives for bridge and road demolitions.

2. A Sensitive Items tracker. Army should have like a bar code on all there items and you just scan it with your phone and it tells you the serial number, the history and age of the item, with the option to have access to the TM.   Call me lazy but taking a old green notebook to the field to write down your entire team/squad serial numbers just sucks

3. Foreign/threat mine apps.  There are thousands of rounds and munitions around the world.  Why not have an app that you can simply take a picture of a piece of ordnance and scan it in, and the app tell you what it is your looking at, type of explosive, country of origin, etc..

Those are just a few ideas.  If you make any and get some money out of it feel free to throw some my way :)
