Progressive Web Applications are a relatively new concept in the mobile and Internet world. PWAs are developed using specific standards and approaches to create apps that take advantage of both native and web application features.
Thanks to the concept of Progressive Enhancement they work no matter what browser you use. PWAs give users a great experience on every modern smart device – on the phone, tablet, PC, you name it. Even though they are ‘just’ web applications, PWAs act like a regular native app (with some limitations and device and OS differences of course).
