Microsoft said Friday it has purchased the office mobile app LiveLoop, which allows multiple users to collaborate on PowerPoint presentations simultaneously.

The purchase is the latest by tech giant Microsoft, after recent acquisitions of other mobile apps for professional use.

'We are excited to welcome the talented team from LiveLoop to help build great collaboration across Office applications, part of our strategy and vision to reinvent productivity,' Microsoft said in a statement.

The tech giant did not say how much San Francisco startup was purchased for.

LiveLoop allows users to share PowerPoint presentations -- a Microsoft Office program -- and PDFs online among collaborators who can access and synchronize the material from any mobile device.

'You can view and present from any device, including a smartphone, so whether you're an attendee or a presenter, you can take your next meeting from the beach,' the LiveLoop website said.

The California startup said it is no longer accepting new users and will close shop on April 24, advising users to back up data before then.

In February, Microsoft bought the popular calendar app Sunrise, after purchasing the email app Acompli in December.
