I decided to make an Android app for my Bible memory verse site (created using Django). The main motivation for the app is to get rid of the unnecessary and annoying address bars and status bars when using the site on an Android phone. The site is already designed to adapt to mobiles, so I'm not creating a native app — I just want a better way to access the web app from an Android phone.
I tried appsgeyser, but discovered they put adverts on your site, which I definitely don't want — this is an entirely free app, for a free (and ad-free) site.
