Who builds Cornerstone
Michael
Founder & Developer
Cornerstone is built and operated by one person. I write the code, author the Catechism and quiz content, record and edit the guided devotions, run the releases on both app stores, and answer the support email myself. There is no team, no agency, and no outside funding behind it.
Cornerstone publishes on the App Store under my own name and on Google Play under the developer account SacredSoft Apps, which is mine. Both developer pages are linked below so you can confirm that directly with Apple and Google rather than taking my word for it.

What is live today
Cornerstone is a shipped, publicly downloadable product on both major app stores, not a preview or a waiting list. Anyone can install it right now, free, with no account required. What is in it:
The complete 73-book Catholic canon in four translations, with optional audio narration. A verse-by-verse commentary section drawn from the early Church Fathers. A structured Baltimore Catechism course. Daily quizzes with streaks and progress tracking. Guided audio devotions covering the Rosary, the Divine Mercy Chaplet, and the Angelus. Reading plans, and a prayer section with an examination of conscience.
You can see the app itself on the home page, and read why I built it in the story.
