First, let me say that although these "web apps" are formatted for the iPhone and iPod Touch's screens, they can be viewed with any web browser on any computer. They're really just tall, narrow websites. (They can be used on some non-Apple cell phones too, but since screen sizes and browser capabilities vary so widely, I can't guarantee anything.)
You can install any of these web apps on your iPhone or iPod Touch's home screen, where it will act just like a "regular" tap-to-launch app—as long as you have an internet connection, of course. Here's how to do it:
1. Use your Mobile Safari browser to go to the app's web address (see descriptions below). Tap the "+" icon at the bottom of the screen to create a new bookmark:
2. Tap the "Add to Home Screen" button to create an icon on your home screen that behaves just like an app.
That's all there is to it! And now, here are my web apps. I hope you find them useful. (For commercial iPhone/iPod Touch apps that I've found useful, see "A few of my favorite things.")
