Microsoft recently acquired the Acompli e-mail client, which it just relaunched as Outlook on the iPhone, and now it may be about to do the same thing with Sunrise, a popular cross-platform calendar application. The firm recently acquired Sunrise for more than $100 million, according to TechCrunch.

I've actually been using Sunrise on both iOS and Android for a long time now, and have praised its simplicity and gorgeous user interface. It also easily syncs with clients such as Google Calendar and Exchange, or even your Facebook calendar. It could fit well into Microsoft's ecosystem, and it's plausible it will be rebranded, though TechCrunch says that won't happen just yet.

The news outlet explained that, according to its sources, Microsoft plans to allow Sunrise to exist as a "standalone" product, instead of one that's completely integrated with Microsoft's own clients.
