AppMarks is a web desktop for your iPhone’s web browser.
AppMarks runs in Safari and presents icon “appmarks” of your favorite web apps, widgets, and sites. Simply tap an appmark to launch it or use the toolbar to rearrange, add, or remove appmarks.
The first time you launch AppMarks, it is set up with sixteen appmarks to get you started. To add your own favorites, tap the “+” button and enter the title and URL. To remove appmarks, tap the “Edit” button and tap the red “-” marks. After you have customized AppMarks, you can bookmark it to make it easy to use your appmarks.
