About

John Beatty runs Tercaet, LLC, a software development company founded in 2010, specializing in iOS app development and Ruby on Rails web applications.

We have shipped multiple iOS apps to the App Store, including the popular Pocket Angelus, Pocket Rosary, and Pocket Chaplet prayer apps with millions of combined downloads and excellent user ratings.

On the web, we publish tutorials and guides at Single Interest, Many Thoughts, covering AI agents, development workflows, and the craft of building software with Rails and modern frontend tooling.

We are available for consulting work on iOS (Swift/SwiftUI) and Ruby on Rails projects. If you have a project you'd like to discuss, please get in touch.
