- A WebApp is a web site that has been optimised for use on the iPhone. Typically it will have an icon which will show up when you use the Add to Home Screen option in Safari. All of the WebApps here are ones that I keep as a Home Screen icon rather than relegated to a Safari Bookmark. If a WebApp gets removed from my iPhone, it'll get removed from here too. Click on the buttons above to chose between showing the Apps sorted by category or when I last added/updated a review
