Sandbox Web Browser
A Web browser that allows you to restrict users to a predefined list of allowed websites.
It's perfect for the classroom, kiosks, places of business, and your home. After installing the app, launch your iDevice's Settings app and scroll down until you find Sandbox. This menu will allow you to customize everything from allowed websites and bookmarks to the message that appears for restricted pages. You can also lock the configuration settings with a passcode to prevent changes.
