Offline Mass PropersThis 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.)

I love this app because I am very forgetful and I often leave my Liber Usualis at home (that thing is heavy). This app very convenient and saves me a lot of time from flipping many pages of Chant also the Propers are already laid out and there are options for the user to use whatever Calendar they have in their Parish. I also love that there is an option to use the Psalm toned Mass Propers. I hope that more apps like this would be made. Thank you very much!

Absolutely amazing app. Complete godsend. Makes practicing so much easier so I can direct schola better. App let's you pick ANY MASS, change starting pitch, complete playback, change timing, shows vocal range. Will definitely be recommending it to everyone I know that sings chant!

Could do with an update based on some notational errors now corrected on the Gregobase site, but otherwise an incredibly useful app. Date of Easter seemingly inflexible as well...!

I was so hopeful, but the audio stops arbitrarily, there is no way to make a favorites list to end constant searching, it is a guessing game to find any chant one is looking for, there is no explanation of the pop-up play button, it is just frustrating & unfriendly & not user friendly whatsoever!

great tool, I would definitely recommend it. the only issue is with playback: if I want to stop the music and "rewind" it to a previous line or anywhere else in the song the playback stops working. the only "fix" is to restart the app.

This app seems "buggy". The sound keeps cutting out mid-chant. Makes it rather hard to learn the flow of a change when the audio suddenly stops. Maybe it's my phone. Samsungs are known to be temperamental. Uninstalled.

Can you please add the whole preface(Trinity, Advent, Lent etc...) including the solemn and ferial tone it has only the Dominus vobiscum to dignum et justum est. Please the app was great but it lacks prefaces which is very useful. Gratias!

Great app! Only concern is when trying to play the chants, it inconsistently stops playing. And sometimes doesn't make any sound at all.
