Gmail has become an extremely popular email service with more than 1.5 billion users worldwide. Businesses have also been rapidly adopting Gmail and, more recently, G Suite—which includes apps such as Drive, Docs, Sheets, Slides, Calendar, and Meet. More than 5 million paying businesses now use these applications to work more collaboratively and increase productivity.The main drawback of G Suite is that people must use a traditional web browser to access its applications. However, browsers were never meant to serve as UIs for complex cloud-based applications.
