This week’s top five business apps for tablet users  include productivity apps, a web browser, and a security suite – and Cube Time & Expense Tracker, the first app in our roundup got the spotlight. The app’s title covers its core functionality, though the developers went much further than that to deliver more features, thanks to deep integration and other elements. It was featured as Forbes’ “Must-Have iPad Apps For Professionals.”

Cube Time and Expense Tracker

One of the biggest advantages this app delivers is integration with Google, Google Apps, Yahoo  and AOL, so that users don’t have to sign in separately for each service. In order to use it you have to subscribe to the developer’s cloud sync service, but that does have its benefits: online backup. That comes in addition to a whole host of time tracking and management features, including expense tracking, a lot of customization and more.
