About the app

Last updated: June 2026

Hi, I’m Mateusz Zaremba — a husband, a father, and a software engineer. Walking with Mary is a small app I built for my wife, and for any Catholic mother who would like the same companion through her pregnancy.

I’ve had an idea of a Catholic pregnancy tracker for a while now — one that would incorporate Catholic values into pregnancy tracking.

My wife and I are expecting our 5th child to come in December ’26. She noticed her pregnancy coincides with Holy Mary’s. She’s been manually tracking Marian feasts to equate her pregnancy to Hers. And the idea for Walking with Mary was born.

I’ve decided to release the app for free, without any subscriptions, and I intend to keep it that way, always.

However, there is associated cost with releasing an app on iOS and it’s $100 per year. The times are tough and we are all struggling, especially families. If you can, and would like to support my family and the development of this app, please consider supporting the developer.

I hope you will enjoy Walking with Mary and it will be a valuable addition in the most amazing anticipation a human can be in.

Yours in Christ,

Mateusz
