Upwork, formerly Elance-oDesk, is a global freelancing platform where businesses and independent professionals connect and collaborate remotely. Upwork allows clients to interview, hire and work with freelancers and agencies through the company's platform. The platform now includes a real-time chat platform aimed at reducing the time it takes to find and hire freelancers. To ensure the freelancers are billing fairly for jobs billed hourly, the platform offers a time sheet application that tracks time and takes screenshots while the freelancer is working. Upwork has a mobile app for both Android and iOS, as well as a time-tracking app for Windows, OSX, and Linux.
