Very interesting and new project no download no install and no update with the ability to work off line concept is really interesting , an app store for progressive web apps is unique idea . I still would like to know the idea behind a cloud based app that can work offline too ! how this gonna be achieved ?
Cloud based because it used through web. You will not have to download it. Just like browsing normally in the internet which does not consume your device memory. When you search something in the web, you can open as much windows as you can but your device memory will not be affected, unlike installed applications, they are in your system, has occupied part of your storage.
