The MassExplained app is a comprehensive multimedia learning experience focused on the Roman Catholic Mass. It is totally approachable and thoroughly entertaining!

"Solid liturgical scholarship and cutting-edge technology."
—Patrick Madrid, Catholic apologist, author and EWTN host

Hundreds of photos, drawings, charts and graphs provide a visually stunning experience. But the MassExplained goes way beyond that with a multisensory experience only possible on your iPad:

Navigate 360° images of towering cathedrals, inspiring pilgrimage sites and ancient ruins.

Rotate meticulously rendered liturgical vessels and ancient artifacts.

The works of the masters help illustrate the evolution of the Mass.

Explore possible Emmaus sites, follow Paul's missionary journeys, discover where saintly relics are venerated today.

Prayers in Hebrew, Greek, Latin and English as well as Gregorian chants and other liturgical music take center stage.

Often incorporating 3D animations, the videos shed light on various aspects of the Eucharistic Celebration.

Zoom in to discover the intricacies of medieval illuminations and marvel at the brushwork of the great masters.

The MassExplained app explores the roots of each section of the Mass. It is packed with scriptural references, quotes from the Church Fathers, the Catechism, councils and encyclicals.

• Make your weekly Mass attendance come alive!
• Understand the reasons for the Mass, not just the rubrics!
• Pass on the love of the Liturgy to your children!
• Discover the influence of Scripture and the witness of the early Church on the Mass!

"Vivid and fresh. A must-have app for the New Evangelization."
—Brandon Vogt, author of "The Church and New Media"

Read with confidence knowing that the content is in line with Church teaching. The app has received two declarations from the Catholic Church:

• The Nihil Obstat, Latin for "nothing hinders", affirms that the app contains nothing contrary to faith or morals. It was granted by Monsignor Terence E. Hogan, SLD Dean, School of Theology and Ministry, St. Thomas University, Miami, FL

• The Imprimatur, Latin for "let it be printed," is an official declaration that a work may be published. The Imprimatur was conferred by The Most Reverend Thomas G. Wenski, Archbishop of Miami, FL

• The app has also been reviewed by the United States Conference of Catholic Bishops (USCCB) and the International Commission on English in the Liturgy (ICEL).

"The future of Catholic publishing has arrived."
—Lino Rulli, best-selling author and host of "The Catholic Guy" on SiriusXM

—The Most Reverend Thomas G. Wenski, Archbishop of Miami

Please note: The Mass Explained app focuses on the Ordinary Form of the Roman Rite—the Mass with which most Catholics are familiar. The app also frequently references the Extraordinary Form of the Mass, also known as the Latin Mass.

This first volume addresses the Introductory Rites and the Liturgy of the Word. A future second volume will cover the Liturgy of the Eucharist and the Concluding Rites.

The Mass Explained app is designed to work in vertical orientation only.

A beautiful experience

When I first looked at the description of this, I thought it might be primarily for classroom type activity. The cost sort of put me off then the intrigue of what could be worth this much captured me and I purchased the app. Within a few minutes of starting to read, it was obvious how much effort and research had been put into this work. The graphics, the pictures, the descriptions, the history are all beautifully done. There is no way that a simple textbook could do justice to the masterpiece that is assembled in this work. I have been a Catholic for 68 years and have never found anything more interesting or educational about my faith than is assembled here. Whatever the cost of the next segment of this , sign me up.

Worth every penny!

Beautiful, elegant, seamless, Incredible!! Only ADD I can think of would be the ability to Highlight &/or take Notes. But I can just as easily use my notebook app in split screen.

As others, I too was hesitant on purchasing because of the price. For over a year I have gone back & forth, but decided to go ahead and treat myself- thinking it may help me w/ my own growth & understanding, as well as help me as a Catechist w/ my students.

I am so thankful that I did. This is an incredible app, w/ so much stuff hidden all through out. W/ everything included, and such a seamless app, I would even pay more..

Amazing App

I'll be honest - I was a little put off by the price at first, but after reading about the app I decided to give it a try. I've never looked back since. It is so worth the money. I've read a lot about the Holy Mass but nothing beats seeing with the eyes. The background information fills in so many gaps. You won't be sorry.
