The navigation paradigms on iOS and Android are different. On iOS you have a swipe-back gesture to navigate back in a navigation stack. On Android you usually use a navigation drawer that slides in from the left side. Felgo Apps abstracts these navigation differences and allows you to use just a single Navigation component, that works cross-platform.
Did you optimize your app for smartphone AND tablet already? This can be a tricky challenge, because with wider screens you can show more information in your app and make the user experience even better. If you optimize for smartphone only, you’re reducing your potential for success.
With Felgo, you don’t need to change your existing code but can use the same source code for phones & tablets. You get a “tablet view” with a navigation page on the left and the actual content page on the right automatically when the screen gets bigger.
