Ad Orientem is a reverent companion for praying the Byzantine Daily Office (Horologion), reading the daily Scriptures, and keeping the rhythm of the Church's year — in your own tradition. It is designed to be quiet, beautiful, and faithful — no ads, no clutter, no notifications competing for your attention. Just the prayers, the readings, and the saints of the day, in English and Spanish. ——— FOLLOWS YOUR TRADITION ——— Choose the calendar your Church keeps, and the whole app follows it — the date of Pascha, the tone of the week, the fasting rule, the movable feasts, and the saint of the day: • Byzantine Catholic — Gregorian calendar and Pascha (Ruthenian, Ukrainian, Melkite, Romanian and other Greek-Catholic Churches in union with Rome). • Orthodox — New Calendar — Revised-Julian fixed feasts with the Orthodox (Julian) Pascha (Greek, Antiochian, Romanian, Bulgarian, OCA). • Orthodox — Old Calendar — Julian fixed feasts (+13 days) with the Orthodox Pascha (Russian, Serbian, Georgian, Mount Athos). Switch for the day, or set a permanent default. ——— FREE, FOREVER ——— These are always free — no account, no payment: • Orthros (Matins) — the morning office, proper to the day, tone, and feast. • Vespers — the evening office, with Phos Hilaron and the propers of the day. • The Jesus Prayer (Hesychia) — a daily penitential psalm, with optional gentle reminders. • Saint of the Day — shown at a glance in the header of every screen. • Explanations of the tradition — the tones, the fasts, and how the calendar works. ——— FULL ACCESS (ONE SUBSCRIPTION) ——— A single subscription unlocks everything below, in both English and Spanish: • The Hours — Midnight Office, First, Third, Sixth, and Ninth Hour, and Compline. • Divine Liturgy of St. John Chrysostom — the people's parts in clear bilingual layout, with today's Epistle and Gospel. • All 365 daily Scripture readings — Douay-Rheims in English, Biblia Platense / Torres Amat in Spanish — with the freedom to browse any date. • Saint of the Day — the full synaxarion life and commemoration. • The liturgical calendar — movable and fixed feasts, the Tone of the Week (Octoechos), and daily fasting rules. • Prayer journeys — guided rules (such as a 40-day Jesus Prayer) with gentle, optional streaks to keep the rhythm. • Intercessions — a community board where the faithful submit and pray for one another's intentions, automatically translated between English and Spanish. Price: $0.99 / month, with a 14-day free trial. Cancel anytime in your App Store settings. ——— ALSO ——— • Fully bilingual English / Spanish — every prayer, hymn, reading, and saint life. • Dark, reverent theme inspired by the gold and lampblack of Byzantine icons. • Offline-first: the daily office and the calendar need no internet connection. Ad Orientem — facing east, toward the rising Sun of Righteousness. For questions, feedback, or to request a saint or office be added, please use the support link in this listing.

May your prayer be fruitful. ### 1.3.0 — 2026-05-26 Version 1.3.0 - our biggest update yet. • Intercede: a private, anonymous community where you can post short prayer intentions and commit to praying for the intentions of others. Every intention is automatically translated between English and Spanish so the whole community can pray together. Pinned intentions appear at the top of every Hour and inside the Great Litany at Orthros and Vespers. • Hesychia: a new tab built around the Jesus Prayer, a daily penitential psalm, and an optional reminder that pings you every 15, 30, 60, or 180 minutes - or never. Choose your own rhythm. ### 1.1 — 2026-05-20 • Fixed an issue on the subscription screen where the free trial length was displayed incorrectly. The trial duration shown on the paywall and the confirmation prompt now correctly match your active offer. • Minor stability and translation improvements. ### 1.0 — 2026-05-18 No release notes. ## Related topics [horarios missa](https://appshunter.io/ios/topics/horarios-missa) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
