Roaming the Big ScreenVisually intensive app Roambi makes a splash on the iPad.

许多应用程序并用ginally built for the Apple iPhone have been making their way to the iPad as well, a transition that makes particular sense for visually intensive, data-rich application features, such as spreadsheets and graphs. That migration is sure to please fans of MeLLmo's Roambi, which since its debut on the iPhone last year became a popular, unified way to access and work with some of the most common spreadsheet, report and graph software programs while mobile.

The iPad version ofRoambi, announced in the spring, sticks to the original vision for Roambi--to render desktop productivity tools onto smaller mobile screens in a functional way that doesn't make them just cluttered, Mini-Me versions of the desktop tools. After downloading the free app to your iPad from the Apple iTunes store, you go online to the secure Roambi Publisher site and upload your Excel spreadsheets, Salesforce.com CRM data, SAP BusinessObjects reports or Google Docs, which are then converted to Roambi's sleek, dark format that makes color bars pop with significance.
