Baltimore Catechism

Baltimore Catechism β Know Your Faith Who made you? God made me. Why did God make you? To know Him, to love Him, and to serve Him in this world, and to be happy with Him forever in the next. The Baltimore Catechism has formed Catholics in the faith for generations β not through feeling alone, but through clear, concrete knowledge of who God is, what He has done, and what He asks of us. This app brings that tradition into the digital world, beautifully designed and built to serve anyone who wants to learn the faith with real depth. Whether you are a lifelong Catholic, a convert finding your footing, a parent forming your children, or someone returning to the faith after years away β this app is for you. LEARN AND MASTER Real knowledge takes more than a single reading. Every question follows a three-step path to genuine mastery: multiple choice, then flash card, then written answer. You only reach mastery when you can write the answer from memory. A built-in spaced repetition system brings back your hardest questions at the right intervals, patiently, until they become easy. THREE CATECHISMS IN ONE The app includes all three Baltimore Catechisms: the first for those preparing for First Holy Communion, the second for Confirmation, and the third β the complete catechism β for adults. The same faith runs through all three, growing deeper at each stage. Concrete doctrinal knowledge is genuinely rare today. Many Catholics, through no fault of their own, were simply never given a firm foundation. They may love the Church and yet feel uncertain when questions arise about grace, the sacraments, or the last things. This app is offered to them too β without pressure, without judgment, at whatever pace suits them. DAILY REMINDER For those who want it, a daily notification offers a gentle prompt to spend a few minutes with the catechism before the day runs away. Formation is mostly a matter of showing up consistently. A little, faithfully, over time. PARENTAL MODE Parents are their children's first teachers in the faith, and this app is built to support that role. Parental Mode lets you quiz your children face to face β the old way β while the app quietly tracks each child's progress in the background. You can see at a glance which questions they have mastered and where they need more time, so you always know where to focus. Each child is different, and this helps you see each one clearly. Light gamification rewards their effort and keeps them encouraged along the way. WHY QUESTION AND ANSWER The catechism's structure has endured because it works. Clear questions, clear answers, committed to memory β this is how human beings have always passed on what matters most. It is not a method for children only. An adult who can answer plainly what the Church teaches about grace, or sin, or the purpose of life, has something solid to stand on. Something to return to in uncertain moments. Something to pass on to the next generation. That is what this app is for. Catechism Full Access is an auto-renewable subscription ($4.99/month or $40/year). Payment is charged to your Apple Account at confirmation of purchase, and the subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://wlmr.github.io/catechism-app/privacy/
