Now that speed of applications is a big issue, I think this project is timely and very practical. Since applications have issues on speed and availability. YAPPADAPPADOO project solves these problems by using low memory and offline applications. This will really mark on the mobile app history.
Sometimes its not just the applcations that are slow, sometimes it is the internet connections that determines the speed of browsing also, but with PWA it will consume less data.
Ya one of the advantages of web applications is it consumes less data, less memory, and more faster than regular phone applications. And what i like here is since it is in the web it is linkable and also shareable. Before i had a hard time finding ways in how to link my facebook and twitter account.
