This is an excellent app, well put together with a good set of Reformed confessions and catechisms. I also like that the scripture references are shown in-app without taking you away from the paragraph or question you're studying. One issue is that, on my phone at least, it's not possible to see the text box on the catechism questions while I'm trying to type the answer. This makes it impossible to see if I've got any typographical errors, or indeed what I'm typing at all. I'd love to see this fixed so that I can use it to its full potential. Nevertheless, thanks for the great resource!
