Have you tried Angular or React? They are frameworks for creating single page WebApps where the DOM is updated on a single webpage, what this means is that your app only loads once and thereafter it is as smooth as a native experience. What you can do is build one menu interface and then have multiple apps all running in the same project. Google Docs is a good example of this. Angular is easier to manage, but personally a bit jarring to get into and understand, whereas React is a bit messier, but easier to pick up.
