The Best Catechism and Theology Learning Apps
Memorize catechisms, learn theology, and study confessions of faith.
Learning catechisms turns scattered theology into organized memory, and the best apps make it stick through review drills and clean design. Heidelberg Catechism and New City Catechism offer free pathways through two of the church's most durable summaries - Reformed and evangelical traditions respectively - while Catechism.app bundles five major confessions into one paid iOS library, and Reformed Forum adds audio lectures on systematic theology. The choice depends on whether you prefer quick daily review or deeper study.
Most catechism apps are free or low-cost, and almost all let you choose your preferred translation and question format. Look for spaced-repetition drills if you're memorizing, or simple text if you're reading for understanding. Start with the free options and upgrade only if you want the full library or advanced study tools.

Heidelberg Catechism
A small, free, single-purpose app that puts the full 1563 Reformed catechism in your pocket with a Lord’s Day schedule and a memorization drill - the kind of tool that does one thing and does it well.
Reformed Forum
A confessional Presbyterian podcast network and online academy that treats systematic and biblical theology as serious, lifelong study - and assumes you want to do the reading.
New City Catechism
A short, modernized catechism with deep Reformation roots, packaged as a free weekly habit for adults, kids, and whole churches - and that is the whole pitch.
Catechism.app
A single iOS app that puts five major Reformed and evangelical catechisms in one searchable, memorization-friendly library - for the price of a coffee.
Frequently asked questions
What is the best catechism app?
Heidelberg Catechism is an excellent free option for Reformed teaching, and New City Catechism is the go-to for a modern evangelical summary. Catechism.app bundles five major confessions, making it the pick for readers who want multiple traditions in one place.
Are catechism apps free?
Several are. Heidelberg Catechism and New City Catechism are both free with no paywalls. Catechism.app and Reformed Forum are paid, but they offer the most content and study depth in the category.
Can I memorize catechisms with these apps?
Yes, most include question-and-answer drills designed for memory work. Some use spaced repetition (showing you a question at lengthening intervals) while others let you quiz yourself freely. The comparison table shows which drill methods each app supports.
What's the difference between catechism apps and Bible study apps?
Catechism apps teach you what the church has confessed about Scripture, organized by topic. Bible study apps help you read and search the biblical text directly. They're complementary - catechisms teach you the tradition's take, then you verify it in Scripture.
