Excellent help. Very usable.

Using this with my two boys (8 and 5), and it’s a very easy way of practicing the shorter catechism. Very cool feature that lets you blur the answer while looking at the question, and then simply tap the screen to show the full answer. I also LOVE that it has not only Scripture references for each Q&A but it provides the full text of each reference right there below the answer. It’s vital to me that I help my kids see how each of these answers is derived directly from numerous portions of Scripture. And this feature makes it REALLY easy to immediately do that for each question/answer.

Improved and really a great resource

I downloaded this app a few years ago and have left it on my iPhone but haven’t really been drawn to use it much. I just opened it again recently and the new look and addition of other historic, reformed catechisms makes this a great resource. I am a seminary student and I use the Westminster Standards and Heidelberg Catechism a lot for teaching and study. This app makes it easy to use these wonderfully rich and vital resources.

This is an excellent app to have the various catechisms and ways to learn them all in one place. These are essential for correct Biblical doctrine and theology. I love that they also have included the children’s catechism. Highly recommend for any professing Christian Believer.
