I have over 100 iPhone apps on photography. Some do things no other app does, or it may do one thing thing better than another app. However, in using these apps, you forget what does what, especially when you do not use one app for weeks at a time. I need an app management tool. Something that will let me make notes about each app, so I can refer back to my notes as I need to. I need a app cheat sheet. It I could write iPhone apps, I would make one.
