Orthodox calendar · iPhone and iPad
One answer, in food words, for the calendar your own parish keeps. With the saints of the day, the prayers, the Psalter and a scanner for food labels.
Free for iPhone and iPad. Today's fast and the calendar are free always.
Old and new, Greek practice and Slavic, with the Serbian, Russian, OCA, Romanian and Bulgarian churches' own names and red letters. Every fasting Wednesday and Friday marked.
Everything is bundled. No account, no sign-in, no tracking and no data collected.
The app states the general discipline of the Church. It is not your confessor, and it says so.
What it answers
The fast in food words, allowed and set aside in two columns. Not sure about a packet? Scan its ingredient list, in 36 languages.
A month grid with every fast day marked, an agenda beneath it, and the feasts and fasts ahead.
The feast and the saints of the day, with lives written for Askesis and a portrait beside many of them.
The morning and evening rule, the day's Epistle and Gospel, and the Psalter by kathisma.
224 fasting recipes from Greek, Serbian, Russian, Romanian, Georgian and Levantine kitchens, each matched to what the day allows.
Where it comes from
Two full years, both calendar styles and both fasting practices, tested on every day. Greek practice is checked against the Greek Orthodox Archdiocese's planner, which is published through August 2027; the last four months of 2027 are rebuilt from the planner's earlier years until it publishes them. Slavic practice is checked against a calendar kept to the OCA's rubrics, with each disputed day checked against the text of the Typikon.
One rule above the rest. Your priest's guidance for you always overrides the app, and the app says so on the way in.
Screens from the app.





Every day of 2026 and 2027 carries its appointed readings in Slavic practice, and in Greek practice through August 2027. Later years come in updates.
The Old Testament is Brenton's Septuagint of 1851; the New Testament is the World English Bible, adapted to Orthodox usage against the Patriarchal Greek text of 1904. Your parish may read another.
The scanner reads printed ingredient lists. A scan can miss an ingredient, and the app says so; when it matters, read the label yourself.
The app and its texts are in English. The scanner reads labels in 36 languages.
Free forever
Today's fast, in full, and the whole calendar. The fast level, where you stand in the season, the feasts ahead, the readings, the day's saints, and the reminders the evening before a fast or a feast.
Askesis Pro adds the label scanner, the prayer rule, Habits, the Kitchen, the lives of the saints, Holy Scripture, Discover and the widgets.

What the fast is for, and how to begin.
How the calendar is tested and sourced.
Every fast, on the new calendar and the old.
Clean Monday to Pascha, and what the fast asks.
Ten years, beside Western Easter.
Why, when, and the fast-free weeks.
Both. Choose your church once and Askesis keeps its calendar, old (Julian) or new (Revised Julian), and its fasting practice, Greek or Slavic, for every day of the year.
Point the camera at an ingredient list and Askesis says whether the food is allowed on today's fast, and names what the fast sets aside. The photo never leaves your phone.
Yes. The calendar, prayers, Scripture, lives and recipes are all in the app. There is no account and no data is collected.
No. It states the general discipline of the Church. Your priest's guidance for you personally always comes first.
No. These churches are a separate family of churches, not in communion with the Orthodox Church, and Askesis does not cover their calendars or fasts.
No. Askesis is made for iPhone and iPad only.
One person builds this. If a day is wrong, send the date, your jurisdiction, and what your own calendar says.
