Stephen's Web ~ What Are Progressive Web Apps? | Education 2.0 & 3.0 | Scoop.it
A progressive web app is an application that works well on a mobile device but also supports older-style browsers (hence, they're 'progressive'). As well, they live on the web, not on your device. "Like the traditional web apps we use today, they’re hosted entirely on the application’s servers. If a developer wants to update their progressive web app, they update it exactly like they would update the web app—on their servers." What's new is that the major developers are gradually working toward a progressive web app standard.
