Dropbox has released its Mailbox email client for Android devices.
The cloud storage company has also announced that a desktop beta version of the service is also in development for Mac computers.
Already available for iOS devices, Mailbox arrives on Android with new features, such as an "auto-swipe" function that lets users automatically archive messages.
The application has also introduced Word, Excel and PowerPoint integration as part of a collaboration with Microsoft dubbed Project Harmony.
Dropbox says that the desktop version of Mailbox will feature a minimal design and trackpad gesture controls. Users can apply to take part in the beta via the service's website.
The Android edition is now available from Google Play as a free download.
