Peerio is a desktop and mobile productivity app that combines messaging with cloud file storage and sharing, as well as contacts management and everything else you need to be productive. Peerio does what you'd expect from a Gmail + Google Drive hybrid, except it comes with end-to-end encryption built in from the ground up.
