Know what applies today
The app brings the day, fasting and abstinence context, and source access into one place—ready whenever the question comes up.
Catholic fasting, made clear for today.
Understand the Church's discipline of fasting, abstinence, and Friday penance—then carry that clarity through the Church year with the app.
For iPhone and iPadA discipline ordered toward prayer.
Christian penance belongs with prayer, almsgiving, charity, and conversion. Clear guidance supports that life; it does not replace it.

Clarity for the day. Support for the practice.
The website gives the immediate baseline. The app keeps regional context, planning, reminders, sources, intentions, and fasting history close at hand.
Keep a personal fast with intention
Set a target, name an intention, and keep the reason for a voluntary fast close at hand. Personal practice never changes what the Church requires.
Rooted in the discipline of the Church.
The universal law names every Friday and the season of Lent as penitential times. In the United States, the bishops provide the complementary norms for members of the Latin Church.
Catholic Fasting is an independent devotional aid, not an official Church or USCCB publication.
Your practice stays yours.
Fasting history, intentions, notes, and settings stay on your device. The app requires no account, and Catholic Fasting does not operate an app backend that receives user-created app data.
