iMass removes boundaries for the spread of the Traditional Catholic Mass. It brings the Latin Mass to the ends of the earth. iMass provides access to the Mass - anywhere, anytime. Are you unable to attend Mass, either because of health, distance or unavailability of a Latin Mass? iMass streams the Mass live from different locations around the world, or you can view the Mass of the day or the Mass of last Sunday on demand, anywhere, anytime. The broadcast Masses are celebrated in the Extraordinary Form by the Priestly Fraternity of St. Peter. Are you traveling and would like to find your closest Latin Mass? The iMass Map is continuously updated by users of the app and will eventually show every Latin Mass location approved by the Catholic Church. Complete with Mass times and driving directions. Suppose you don’t want to carry around your missal or you have forgotten it - no problem, with iMass you can follow the Mass with our easy to follow missal. The app also includes the Breviary (Divine Office) and the Rituale - the book of official blessings for priests of 1962. Just to be clear: you cannot fulfill you Sunday obligation by viewing the Mass on iMass. However, in a similar way to other televised Masses, it is a way to unite yourself to the Mass when you are unable to attend. When sickness or another valid reason excuses you of your obligation to attend the Mass, this is the best way you can unite yourself to the Mass that you are unable to attend. iMass. Mass, Anywhere, Anytime.

Offline Mass Propers This app is an offline version of the chant tools available at http://bbloomf.github.io/jgabc/ It is mostly intended to be useful for containing the Gregorian Mass propers as well as the Gregorian Mass ordinaries as found in the Liber Usualis, and transcribed on GregoBase (http://gregobase.selapa.net) and there may be some mistakes in the chant. If you notice any, they can be corrected in GregoBase (if you go to http://bbloomf.github.io/jgabc/propers.html and find the chant with the mistake, you can click the link above the chant on the left side to get to the GregoBase version of the chant, and edit it there to fix it, or request that it be fixed.)

Chant Tools's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (15.0 vs 17.6). On price, ratings volume, ads and in-app purchases there is nothing between them.
