Nistikon — Orthodox Calendar

Today's fasting rule in plain English, the feasts and saints of the day, a Pascha countdown, and your own prayer rule — bundled for offline use, with no ads or tracking.

What is the fast today? Nistikon answers that question the moment you open it — in plain English, with bundled content that works offline.

Built for Orthodox Christians — from catechumens taking their first steps to lifelong faithful — Nistikon is a calm, respectful daily companion. No ads. No accounts. No tracking. Nothing to sync.

TODAY AT A GLANCE • The day's fasting rule, spelled out: "Wine and oil are allowed today." • The feasts and saints commemorated, with a short life for each • Scripture reading references for the day • A live countdown to Pascha

A 50-YEAR CALENDAR • Every day from 2026 to 2075, color-coded by fasting level • Tap any day for its full detail • New-Calendar and Old-Calendar (Julian) modes • Jurisdiction presets: Greek (GOARCH), Antiochian, OCA, ROCOR, Serbian

YOUR PRAYER RULE • Build a Morning and Evening rule from a library of public-domain prayers • Large, readable type for prayer • Gentle daily reminders — entirely optional, off by default

WIDGETS • Home-screen and lock-screen widgets showing today's fast at a glance

PRIVACY BY DESIGN • Bundled calendar and prayer content works offline — even in Airplane Mode • No ads, no analytics, no data collection of any kind

All prayer texts are public domain (Hapgood, 1906, and other pre-1923 sources); sources are listed in the app. Fasting practice varies — Nistikon follows a widely published simplification, and every fasting screen reminds you to follow the guidance of your own priest.
