The promise

The goal of Medalius is simple: to help you learn and answer about the Catholic faith and to respond clearly to the most common questions about it.

Why Medalius

Depth, with patience.

It is not school catechism nor social-media apologetics. It is a small routine, at your own pace, with official sources at every step.

Study with grounding

Every lesson cites the CCC, Scripture, a Magisterium document or other sources. You know where each statement comes from.

A habit that sticks

3 to 5 minutes a day. Short tracks, XP, daily streak, milestone medals and a weekly ranking — gamification that motivates without pressure.

Truly free

The essentials are free — and stay free. Pro is optional, for those who want to unlock the full library and support the project. No paywall on basic content.

How it works

Four steps. Come back tomorrow.

01

Follow the Medalius journey

The tracks are presented in a structured way so your formation progresses naturally.

02

Do the lesson

An opening question, feedback, a mini deep-dive, 3 to 4 reinforcement questions.

03

Take a phrase with you

Each lesson ends with a summarizing quote — with a clear source for you to keep.

04

Come back tomorrow

Streak +1, next lesson suggested, no invasive notifications. You set the pace.

Library + Tracks

The most searched questions became lessons.

Every frequent Medalius question becomes a gamified lesson, with an official source and deeper study. Same answer, now as a study routine.

All the detailed answers remain available for direct consultation. The tracks are the active way to learn, but the library of questions and answers stays as an always-accessible reference.

Why do we venerate images?

Example of one of the lessons from the "Mary and the Saints" track. The whole structure fits in 4 minutes of use.

"The honour paid to an image refers to its original; whoever venerates the image venerates the person represented in it."

About the project

How Medalius works.

Medalius was born to clear up questions about the Catholic faith in a simple and accessible way — with short answers, clear sources and respect for those who are still asking.

Now that same library becomes a study routine: short tracks with questions, feedback and medals. Small daily steps, in the same editorial line: respectful, well-founded, without confrontation.
