The largest Christian learning platform. And more than a library: Theosis takes you by the hand.
2,308 books of the Church Fathers are overwhelming if nobody tells you where to start. That is what Theosis does. You say what interests you and you get a curriculum that fits, adjusted week by week. 32,000 hours of it are read aloud, so your curriculum keeps running on the way to work.
"I love the app, I've had nothing but a great experience with it."
"Good app to dive deep into the Bible."
YOU ARE TAKEN BY THE HAND
* You pick the subjects you care about, Theosis builds your curriculum from them
* Every week the app asks how it is going and adjusts your goals and your pace
* Reading plans, a daily rhythm and a streak that rewards consistency
* Your next work: finds the book from your interests that fits you best right now
THE LIBRARY, ORDERED BY THE CHURCH YEAR
* 2,308 books in full text, not excerpts and not summaries
* Every book curated and categorised by hand, not by an algorithm
* New categories every week, following the liturgical cycle of the Church, suggesting what belongs to this season
* John Chrysostom, Basil the Great, Gregory of Nyssa, Maximus the Confessor, the Philokalia, the desert fathers
* 2,133 books are narrated, together 32,000 hours of audio across 11 languages
READ IT, HEAR IT OR PLAY IT
* Many books come as a podcast that sums the work up and discusses it
* Many books can be played as a quest, and read in full afterwards
* The Pearl of the Day condenses a book into two or three minutes
* A book of the day, 518 days deep
THE BIBLE, EXPLAINED VERSE BY VERSE
* You read a verse and get an explanation of what it means, right underneath it
* The explanations come from the Church Fathers themselves
* 134,858 commentaries from 316 Church Fathers, each one at its own verse
* 22,048 of the 36,117 verses are already explained, and more are coming
* Word studies in ancient Greek: tap a word and see what it actually says
* Cross references from verse to verse through the whole of Scripture
* Bible reading plans to choose from, so you stay with it daily
QUESTS
* Every quest follows a patristic work or a book of the Bible, nothing is invented
* You play your way through the work with illustrated images, with questions along the way
* New quests arrive every week
* Afterwards you decide whether to read the book in full
COUNCILS AND DOGMATICS
* The ecumenical councils, the creed and the canons, sourced and readable
* What was decided, who argued against it, and why it still binds today
THE LANGUAGE OF THE LITURGY
* Guided sessions on the words of the Divine Liturgy and the responses of the people
* For everyone who did not grow up with Greek or Church Slavonic at home and stopped asking what the priest just said
EVERY DAY
* The saint of the day from the Prologue of Ohrid, with the icon and the audio
* Private notes across everything you read
* A confession preparation that stays behind a lock on your device
* Reading circles, so you go through a book with other people instead of alone

I love the app, I’ve had nothing but a great experience with it.
Not worth the money yet
Inrdmds
The app has a lot of potential with a wide selection of books aswell as lives of the saints daily scripture reading etc aswell as a vast collection of church fathers commentary on scripture if you for commentary specifically I don’t recommend this app Catena is better. Current flaws is the app is quite slow and un organized I don’t mean how it looks just when you click on certain things it brings to a page you have to exit from to get to the page you initially clicked on. Overall this app is a 4.5 out of 10 but has a lot of potential. God bless

Thank you so much for your honest and thoughtful feedback!We’re a small team of young, ambitious Christians who have poured our hearts into Theosis — 15 months of intense, self-funded work. No investors, no big company — just a vision to build something truly meaningful for the Body of Christ.The app already offers one of the most comprehensive Christian-theological experiences available today:– Daily Scripture readings– Lives of the Saints– Over 120,000 patristic commentaries (almost twice as many as Catena!)– A massive and growing spiritual library (2,000+ works)– Audio stories, bilingual liturgies, and moreWe continue to grow every month — in both content and features.Yes, we’re aware that some parts of the app can be a little slower or not perfectly streamlined. But we’re improving that constantly. And we believe it’s worth asking:For this much depth, insight, and spiritual nourishment — is it really “not worth the money yet”?That’s something everyone must decide for themselves. Many users already tell us it’s unlike anything they’ve ever used.With every download and subscription, you're not just getting access — you're directly supporting the mission and helping make this app better for everyone.Thank you for being part of the journey — your feedback helps us grow.God bless you,Your Theosis Team
60$ really?
Turbo scout
I understand you probably think this is a reasonable price for some reason because your a “small group of developers with no big investors” but how do you suppose they his app is going to help if I can’t even use it? Also please add a free trial so that people can know if it’s even worth it don’t let yourself fall into this greed. You have gotten like 10 reviews asking you to do something about this and nothing has been done fix your app.
Developer Response
Hi, we added a free trial AND you can use most of the app for free. We could not offer that in the first year of our journey because we had to get some resources to be able to make the app as wonderful as it is today - please try the new update and lets us know what you think.
60 dollars???
Seraphím
Forced to pay 60 dollars for the “Netflix and audible of Christianity” such a shame to see more Christian’s fall into greed. 60 dollars is just criminal while other apps such as orthoprax charge a fourth of the price for something very similar. Truly a shame to have waited all this time for the development of this app just to be stuck behind paywall this high, and 60 dollars for a year not a life time makes it even worse. Lord have mercy.
Developer Response
Hello Seraphim, Thank you for your feedback. It seems there might be a misunderstanding. Comparing us with Orthoprax shows that there is a lack of understanding of what we actually offer. Our app has a different focus and scope, which we've always clearly communicated, including the fact that it operates with a subscription fee. This helps us continue developing and maintaining the platform, ensuring quality content and ongoing improvements. We are also working on a demo version to give users a better insight before subscribing. We’re sorry if we haven't met your expectations and truly value constructive feedback. However, referring to us as criminal is not only inaccurate but also damaging. We are committed to creating a positive experience for our users, which is reflected in the many 5-star ratings we’ve received across European App Stores from people who understand and support our mission. If you’d like to learn more about our goals and the reasons behind our subscription model, we invite you to explore our website. Creating and maintaining a quality app involves significant effort and resources, but if you have a way to offer something similar for free, we encourage you to pursue it!
