A Digital Cathedral
Free · Designed for iPad. Not verified for macOS.
The Orthodox calendar, the saints and their lives, prayers and services, fasting for every day — in your language, on your phone and wrist, working offline. Free, no ads.
The Orthodox Church's year, in your pocket.
Orthodox Atlas is a calendar, prayer book, and reference for Orthodox Christians — free, with no accounts, no ads, and no tracking.
THE CALENDAR
Every day of the year with its saints, feasts, fasting rule, tone, and scripture readings. Follows your church — Old or New Calendar — with the fasting discipline your parish keeps.
THE SAINTS
Lives of the saints for every day, with their icons, troparia, and kontakia. Each text names its source.
PRAYERS & SERVICES
Morning and evening prayers, preparation for Communion, the Divine Liturgy, Vespers, Matins, and more — readable in ten languages: English, Serbian, Greek, Russian, Romanian, Bulgarian, Ukrainian, Macedonian, Georgian. Download everything for reading without a connection.
THE CHURCHES
A map of Orthodox parishes and monasteries worldwide — find a church near you, with contact details and directions.
EVERYWHERE YOU ARE
Widgets for your home screen, an Apple Watch app with complications, quiet notifications for feasts and fasts if you want them, and iCloud sync that keeps your place in a text across your devices. Works with VoiceOver, Dynamic Type, Reduce Motion, Voice Control, and Switch Control.
Orthodox Atlas is free. No sign-up, no subscription, nothing collected beyond anonymous usage counts. What the Church has prayed for centuries, ready when you are.
Ratings & Reviews
New in 1.2
• My Slava and My Name Day. Mark a saint's day as your own from the saint's page. The day says so when it comes, and a reminder arrives the evening before and that morning.
• Subscribe in Calendar. Add the Church year to your calendar app: every day, or only the great feasts, major saints, Sundays and fasting seasons you choose.
• The hymn library. Every troparion and kontakion in one place, to narrow by kind and tone.
• The saints index, and every metropolis and diocese of each Church.
• Every day by its name. Sundays are named for their place in the year, and each day is titled as your Church keeps it.
• Services and prayers open with what the day and the hour call for.
• A reading says which service it is read at, and a hymn shows its tone.
• A saint with no hymn of their own is given the general one.
• The app holds together at the largest accessibility text sizes.
• Widgets and Apple Watch name the day for your Church.
• Reminders keep coming even when you have not opened the app, and the Wednesday and Friday fast is announced only when it is kept.
And many smaller fixes.
