We touched upon this subject in another thread, but I wanted to explore it a bit further.
As I've posted several times, I'm a programmer and I've been looking for a good reason to get into mobile development, specifically iPhone/Android. I'm currently working through some books on iPhone development, but nothing really gets you down and dirty like working on your own project (following examples in books is nice, but they're usually very specialized). Android is not a problem since I'm a fairly experienced Java programmer already; I just need to get a better grasp on the classes and views the Android SDK presents.
What I was wonder is what kind of things would people like to see in an App? I had an idea at one time to create an app for FFXIV that would have crafting recipes, a skillchain calculator, possibly hooks into FFAH, etc. Since I'm not playing FFXI anymore I let that idea drop, but I was thinking about starting a project for a FFXIV app. If I get enough good ideas, I'll start working on something (I would have to wait until after the game was released, I'd rather not rely on beta data).
