About
Lumen is a free Christian app that keeps the memory of the churches you visit.
More than 149,000 churches, chapels and shrines are already on the map: France, Poland, Québec, Belgium, Luxembourg, the United Kingdom and Georgia. A church is missing? Suggest it in a few seconds and, once approved, it is added to the map.
YOUR MAP OF CHURCHES
• From cathedrals to village chapels: search by name or city, or simply let the map guide you.
• Every church has its own page: photos, Mass times and events, kept up to date by parishes and the community.
• Save a church to visit later, and find it again the day your road passes nearby.
YOUR JOURNAL
• Log a visit in a few taps: the date, the occasion (Mass, pilgrimage, a simple visit), a personal note, your photos.
• Your personal globe and your figures for the year: places visited, cities, countries, favourite place.
• Year after year, your journal tells the story of the road you have travelled.
PRAYER
• Entrust a prayer intention to a place you hold dear: a candle burns there for 24 hours, or nine days for a novena.
• Others will pass by, read your intention and carry it in their own prayers.
WITH FRIENDS
• Follow your friends' visits: their photos, their words, your reactions and comments.
• Share a photo as a story, visible to your friends for a week.
• No strangers, no endless feed.
FOR PARISHES AND DIOCESES
• A free official access: Mass times, events and announcements for parishioners.
• Pages looked after by a parish are marked "Maintained by the parish".
• Become a parishioner of your church to receive its news.
IN ENGLISH AND IN FRENCH
• Lumen follows your phone's language; you can change it at any time in Settings.
QUIET, BY CONVICTION
Lumen is built by volunteers. No ads, no data selling: a notebook you open and close. GDPR compliant, data deleted on request.
Lumen is made for Catholics. Orthodox and Protestant churches are on the map too, with their denomination shown on the page.
