A free program for Android, by Concordia Publishing House.
This app is designed to be a tool to help you read and navigate the Small Catechism, the book of God that contains the answers to the questions we have about God’s will and the way we can live to please him. The questions are organized in a way that makes it easy to find the answers, so that you don’t have to spend time reading through the whole book. It also provides you with a table of contents so that you can easily find the chapters and topics that you are interested in.
You can also read through the daily prayers that are included in the Small Catechism. These daily prayers will help you to stay focused on God and the things he wants you to do.
