Four stars for the content. Five minus one due to the over abundance of reformed theologians and under representation of the Wesleyan position.
 
Zero stars for the actual application. This thing is a dumpster fire. Accessing through the web browser on desktop or mobile is 1000% better.

+ 1 bonus star to help others to find this great resource. Just go to the website and dont bother with the app. Download it once to boost its rating for others to find.
