Just to confirm: YAPPADAPPADOO will be an apps store whose apps will be PWA exclusive?(PWA equals web app, meaning no native apps available?)
Web apps are literally apps accessible on the web using chrome, firefox, safari, etc. It would be like saving the webpage kind of thing that's why there is no download or install nor much space needed. Safari/iOS is not yet fully PWA compatible and slightly difficult to "install". Will they address this issue?
Well, "native apps" are usually accessible through their website i.e. they have an online platform accessible through web browsers e.g. Facebook, Twitter, etc. In case this will be a PWA store, then that will be what the store would offer, probably.
