Ideas or needs for new applications

[robj]

I'm learning Objective-C and Cocoa, I learned the basics some time ago and I'm doing some sample applications, but I would like to make one that somebody want to use and not spend my time and efforts in doing worthless things

So, I would be great if anybody has any ideas or needs to share with me

If all this get a good point, there are benefits from both, You'll have an application that you wanted to have and I'll keep learning and proud of doing something useful

Thanks
