Antidoron
An Orthodox prayer book that knows what day it is. The daily rule set for today, the whole Bible, the Psalter, the Hours, and the parish inside. Free, with no account.
What had to be true.
An Orthodox Christian's morning prayers depend on the day: the tone, the fast, the saint, the readings. The printed book cannot know any of that, so people flip between the book, a calendar app and the parish email. Antidoron is one page that already knows the day, with the person's own rule in the order their priest gave it, for the New Calendar and the Old. The founder built it for his own parish first.
The work, piece by piece.
A calendar engine with corrections
Each day is assembled once from an open liturgical calendar and cached for a year on both reckonings. A priest can correct any day for everyone without an app update; the apps keep weeks of days on the phone for a church basement with no signal.
The whole Bible, three ways
The Septuagint in English with the Church's psalm numbering, the King James with the deuterocanon, and a modern English: 103,000 verses loaded, full-text searchable, downloadable in whole for offline reading.
The Psalter and the Hours
Twenty kathismata with the day's appointed reading, the four Hours, Great Compline and the prayers at the chalice, set from public-domain service books with every translator named on the page.
Native on both phones
SwiftUI on iPhone, Jetpack Compose on Android, the same book on both: a page-by-page runner for the rule, a prayer rope with a knot of haptic per prayer, the rope from the lock screen, and a morning line built on the phone with no server.
Private by construction
No account to pray. The names a person prays for, their notes before Confession and their rule never leave the device. Every table in the database has zero direct grants; the apps talk only to narrow functions.
A parish layer that asks nothing new of the office
Weekly services with reminders, the bulletin forwarded to one address, Confession times, and giving that points wherever the parish already takes gifts.
Desktop and phone.
What's inside: SwiftUI, Jetpack Compose, Next.js, Postgres with zero-grant RPCs, a liturgical calendar engine, full-text search, local notifications.
