Katekisimu Ndogo is an Android application developed by AlberaInfoTech that provides a foundation for learning the Catholic faith. The app is based on the Small Catechism of the Catholic Church, published in 1998 by the Archdiocese of Songea. It is divided into four main sections, each of which contains several questions and answers that are essential to learning about the Catholic faith. The app relates the teachings to the Word of God from various books of the Holy Bible.

The first section, Imani, covers the Creed of the Catholic Church, which is divided into 12 main parts, each with questions and answers related to each article of faith. The second section, Sakramenti, provides answers to questions about liturgy, grace, sacraments, the importance of sacraments, and who and when one should receive the appropriate sacrament. The third section, Amri, analyzes all of God's and the Church's commandments and provides answers to questions about virtues, types of sins, temptations, and conscience. The fourth section, Sala Muhimu, is divided into seven parts that deal with various types of prayers for Catholics that are essential to their daily life and activities.
