I just tried to use EasyEDA on my android tablet in chrome. Because you do not need to scroll down in the page, it never removes the navigation bar. This takes up at least 1 inch on my tablet. Chrome on android supports the ability to run web apps in full screen mode if you generate a shortcut on the homescreen. But, the website header must include a bit of code to allow for this. I mostly use the site on a computer, but knowing that I can use it on a tablet makes it great for on the go. If you could add the code needed to support full screen on Android chrome, I would greatly appreciate the work. I am sure that others would as well, and probably did not realize that the site would work at all on mobile. One thing that does not work, and this may depend on the maker of the tablet, is mouse right click. It seems to default as the back button. So, if a tablet/phone is recognized when accessing the site, then a button could be added to the interface to allow for the operations within a right click to display without actually right clicking. This would get rid of the need, if there is any request, to create an android application. The web app would be used anywhere, and with little work to support mobile other than browser differences.
