Who it is for
Why do so many of us find out about a feast day too late?
Here is a problem many Catholics know well.
Paper calendars and parish bulletins help, but they depend on you looking at them at the right moment.
Catholic Reminders is built for exactly these people.
Here is a problem many Catholics know well. The calendar of the Church is rich, but it does not announce itself. A feast day arrives midweek, a fasting day sits quietly on a Friday, and a holy day is mentioned once from the pulpit and then forgotten by Thursday. You remember on the drive home, or the next morning, or not at all.
Paper calendars and parish bulletins help, but they depend on you looking at them at the right moment. A busy parent, a shift worker, a student or someone who travels often is not looking at a calendar at 7 a.m. on a weekday. The result is a quiet guilt about days missed and readings never opened.
Catholic Reminders is built for exactly these people. It helps you understand what your day and week mean in the Catholic faith, and it delivers customized guidance when you need it: the liturgical calendar, feast days, saints, readings, prayers and context for what is happening in the Church. The information comes to you, so remembering is no longer your job alone.
Use cases
4 ways people use Feast days and holy days of obligation, never missed.
- Saint of the daySaint of the day
1. A weekday feast you would have walked past
Picture a commuter who attends Mass only on Sundays and rarely checks anything in between. On a Tuesday morning, a feast of a saint falls on the calendar, and nothing in their routine would have told them.
With Catholic Reminders, the morning alert says that today's readings, the saint of the day and a short prayer are ready. The person reads the saint's short story on the train, says the prayer, and perhaps decides to stop by a church at lunch. The free plan already covers this: today's feast, saint and readings, anytime.
- Week aheadWeek ahead
2. Planning the week before it starts
A parent who organizes meals and schedules for a family needs to know about fasting days and special observances ahead of time, not on the day itself. Guessing on Thursday evening that Friday is a fasting day is stressful.
The parent asks what this week means in the Church calendar. The app lists the feast days, fasting days and Sunday readings for the week ahead. The parent plans meals, tells the family, and reads the coming Sunday's readings together on Saturday night.
- Holy day alertHoly day alert
3. A holy day that falls in the middle of a work week
Holy days of obligation are the ones most easily lost in a packed schedule, because they land on ordinary days. Someone with a rigid job needs notice early enough to arrange time for Mass.
Catholic Reminders puts the calendar in front of you in advance, with a briefing that names what is coming. The person sees it, checks their parish's Mass times on the parish's own website or bulletin, and asks their manager for a longer lunch or an early finish. Confirm local schedules with your parish, since times vary.
- Novena trackingNovena tracking
4. Keeping a novena going
A novena is nine days of prayer, and day six is where many people lose the thread. Life gets busy and the count slips.
Premium includes novena tracking, along with commitments and morning and evening briefings. The evening briefing can remind you which day of the novena you are on, so you pick it up again instead of starting over. Premium is free during the beta.
