Citigroup said Monday that it has launched a mobile version of its CitiManager desktop portal. The management tool allows corporate cardholders to check in on accounts, statements and transactions.

The aptly named CitiManager Mobile lets customers view multiple accounts. It will work on iPhone, Windows, Android and BlackBerry devices.

"The launch of CitiManager Mobile is a significant milestone for us, exemplifying our dedication and commitment to delight our clients through innovation and digitization," said Naveed Sultan, Citigroup's global head of treasury and trade solutions, in a press release.

The software will be available to the New York-based bank's customers in more than 50 countries, in roughly 20 different languages.
