Yahoo snaps up diary mobile app maker Wander

Internet giant Yahoo has acquired New York-based journaling startup Wander for an undisclosed sum, as it continues to flesh out its mobile app portfolio.

The company's flagship product is called Days, which is an iPhone app that encourages users to record daily events as visual diaries with images and gifs. The images are combined into a "day," which can be shared later with friends.

"We've spent the past few years figuring out how to make content creation as habitual as content consumption," the Wander team said in a blog post.

"We're excited to announce that we've accepted an offer to bring our work on daily habits to Yahoo."

Wander said Days will continue as a "standalone entity", although the Wander team will join Yahoo's Mobile and Emerging Products group in New York to work on "exciting" projects.

Yahoo has not disclosed how much it paid for the company, although TechCrunch suggests it could have parted with "north of $10 million".

The purchase follows a series of acquisitions made by Yahoo since CEO Marissa Mayer took charge in July 2012. In that time, it's bought 27 companies, many of which were small start-ups, with the exception of social blogging platform Tumblr.

Yahoo tends to buy small apps to recruit talented young developers to improve its existing products. The team behind the app Stamped, Mayer's first purchase, was folded into Yahoo's Mobile Properties team.

"At some point [in the near future] we'll have to be a predominantly mobile company," Mayer said in October 2012. "The future of Yahoo is extraordinarily bright."
