No one ever said that apps were intended to be helpful. In fact many of them are there purely to entertain us. The latest “useless” but fascinating app that I came across is the iSteam. This app basically transforms your iPod touch or iPhone screen into a foggy window. By blowing onto the screen, or by restarting the app, you can steam up the screen and then draw on it with your finger as you would on a foggy car window. Cool, it is. Useful? I highly doubt it.
