00 · A Catholic & Ignatian prayer app
Welcome to
Cardio Deo.
A gym for the soul.
Built for those who take the interior life as seriously as the physical one. Daily structure, honest tracking, and the full tradition of Christian spiritual practice at your fingertips.
01
Exercise Yourself
in Godliness.
1 Timothy 4:7
The Greek word is gymnaze, the root of gymnasium. Paul was not speaking in metaphor: the soul, like the body, is trained.
Cardio Deo is your daily training log for the interior life. Like a fitness tracker, you bring your own equipment and the app provides a structured plan (Bible, prayer beads, etc.).
02
