Cloud storage company Dropbox is closing down two of its free consumer apps, Mailbox and Carousel, as the company pivots to focus more on its paid file storage service for businesses.

Mailbox, an email app for smartphones, will be shut down in February 2016, with Carousel, a cloud storage and sharing solution for photos, following at the end of March. All photos stored using Carousel will still be available to users directly in the Dropbox app.

The two apps were part of the firms attempts to offer new types of services beyond online storage, a market which is fast becoming increasingly competitive and difficult to monetise as tech giants like Apple, Microsoft, Google and Amazon enter it.

Mailbox was acquired by Dropbox in 2013, while Carousel was developed in-house and released last year. The two apps were intended to be part of a family of apps aimed at integrating Dropboxs key functionality more deeply into everyday life for consumers, but with business users making up a growing portion of the firms revenues, Dropbox has elected to close down both the services.

“Building new products is about learning as much as its about making,” said Drew Houston, CEO and co-founder of Dropbox. “Its also about tough choices. Over the past few months, weve increased our teams focus on collaboration and simplifying the way people work together. In light of that, weve made the difficult decision to shut down Carousel and Mailbox.”
