Hi I am the developer of the iFight App for Android and iPhone. Glad I found this forum. Look forward to sharing ideas with you.
iFight is a funny little app that has many uses. To put it simply it makes weapon sound effects by swinging your phone. Have a friend who is whipped by his girlfriend? Pull out the whip on him. Want to get into a virtual Kung Fu sword fight? You can do that too! Want to do a pretend drive by shooting on your friends? Hook it up to your car stereo and you can do that too!
Video demo of the iPhone version is here: Tingalin iPhone App iFight Pro iPhone App. Droid version works exactly the same but it does not have the background music yet.
You may also find my free app "Knock On Wood" funny. Its FREE and it does just what it says and a little more. You can swing your phone around and make a 2x4 hit sound. Like hitting someone over their head with a piece of wood. If you knock on wood long enough you will eventually encounter a shattered glass effect.
I have a couple of other app ideas that I want to develop for the Droid when time permits.
