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.
I agree with you guys. Sometimes internet connection is the problem. But, with PWA apps you can work offline the apps. This one of the great thing about PWA. Expecting to change the usual things for the better.
