AppMakr is a site which you can create simple apps using a RSS feed. You can create android, iOS and windows 7 apps. There is a free option but your app has ads in it. You have to pay £99 a year for it to be included in the apple app store and £25 for the google play store. You can publish an android app and share the link. You have to go to settings and tick the box accept non-market apps.
An example of an android app is mine which contains all my blog posts. Download the latest version at http://www.appmakr.com/app_manager/builds/install_ota/241205?h=7550adc9d9764c1c72c769c5889fce86.
