About
Lumen brings your calendar and the Church year together in one clear, easy-to-read app.
SEE THE CHURCH YEAR IN YOUR CALENDAR
• The liturgical day and season, in its liturgical color, on every day you look at
• Solemnities, feasts, and Holy Days of Obligation, following the calendar of the United States
• Saints of the day, with obligatory and optional memorials
• Days of fasting and abstinence in Lent and Fridays of penance
• Links to the day’s Mass readings and the Liturgy of the Hours
NEVER MISS MASS
• Lumen checks each Sunday and Holy Day of Obligation for a Mass on your calendar. A Saturday evening vigil Mass counts.
• If none is planned, it lets you know and helps you add one or find Mass times nearby.
• An optional reminder one hour before Mass, when the Eucharistic fast begins
PRAY THROUGH THE DAY
• Optional reminders for the Morning Offering, the Angelus, the Hour of Mercy, the Daily Examen, and Night Prayer
• The mysteries of the Rosary for each day of the week
• A reminder the evening before holy days and days of fasting
• Confession: see when you last went, when you go next, and get a gentle reminder at the rhythm you choose
A CALENDAR THAT’S EASY TO READ
• Large, clear text and strong contrast
• Day, week, and month views, with your own events in front and shared calendars behind
• Important events stand out, overlapping events are easy to spot, and your free time is easy to find
• Type an event the way you’d say it, like “Lunch with Ana tomorrow at 1”
• Search in everyday words, like “when was my last Confession”
• Drive times, a Leave Now countdown, weather, birthdays, and U.S. holidays
SAFE WITH YOUR CALENDARS
• Lumen uses the calendars already on your iPhone, including iCloud, Google, and Exchange.
• It never changes anything on its own. Events are saved only when you tap Save.
• Lock any calendar that isn’t yours to change, such as a parish staff calendar, and Lumen will never touch it.
• Your events stay on your device and in your own accounts.
Also on iPad, Mac, and Apple Watch, with widgets, Siri, and Shortcuts.
