MTG Judge Core App

Judge Core App, the app created with the intention of being the core app for expansion if need be.Supposedly picking up where MTG Judge left off, it has spawned itself into a new project.

- Runs perfectly fine offline
- great for when you're judging overseas
- Searchable offline oracle card database
- Complete Infraction Procedure Guide
- Complete Comprehensive Rules
- Complete Magic Tournament Rules
- Decklist counter
- Quick Reference for items like Penalties and Layers

For the permissions required that it displays when you first install the app, here's an explanation of what they are needed for:
- Permission to access the Internet: For downloading of updated database and other little bells and whistles, eg. downloading the corresponding card image from Gatherer, etc.
- Permission to access your external storage: For storage of images downloaded, and as a temporary storage location when downloading the updated database. This is to prevent any corruption of the existing database in the event of a failed download.
- permission.C2D_MESSAGE and permission.RECEIVE: For GCM message receiving

This app is not endorsed nor produced by Wizards of the Coast Inc., Hasbro nor its subsidiaries.This app is a personal project of Andrew Teo.

Do report any bugs by emailing [email protected] with "MTG Judge Core" as the email's subject.

Important Update:

With regards to other languages, I have no intention of doing so, due to the fact that it would:a) Make the database grow X times in size, where X is the number of languagesb) Also cause the translation to not be from the official documents, which would/might cause confusion, and that is what I wish to avoid at all times

Great app, very complete. However today I was at my PPTQ and needed some oracle texts. The app didn't display them anymore. Neither did it for the rules and IPG. All the items' structures were shown but none of the articles popped up. I uninstalled the app, then downloaded it again. Everything was back to normal. It would be nice to have several other languages added to the app, especially for the oracle part. I know my French and Spanish players would be grateful.

Excellent app. However, I used to be able to download card images from the Gatherer, but that ability no longer functions. An error message reads "having trouble downloading image from gatherer, please try again later." When I do try again, still nothing.

Good, small app with all the needed functionality, but also a few mistakes. If this gets corrected, five stars are surely going to follow: - card databases don't get updated very often. Right now, new Theros, Ikoria, C21 and ZNR are missing. - searching within comprehensive rules is bugged and instead of finding just the clause, also filters it, and cannot be evaded - probably Gatherer's mistake, but finding card images takes very long (download still same speed) I hope this gets better :)

After searching for keywords (like "instant"), if I click a result, the app won't show anything. However it still works well without searching. Hope you can fix it.

When I search for various rules no text shows up. Ex. Searching Miracle in the rules beings up an empty box with no rules text. Using Pixel 4 XL. Fix please?

Oracle database seems incomplete ,could not find Aminatou. Else a great tool.

Thank you for your hard work over the years. This app has been an invaluable asset for so long. It will be hard to replace.

Wil. H. Nov 13, 2019     

Great app will be very much missed and there are no good replacements thanks for all the help this app has provided

How is it possible that my moto G3 is "not compatible" with this app? How can this app cannot work in Android 6? 1 star until it's fixed

App keeps crashing without loading.

An invaluable tool in my judge life. Simply awesome

Updating to have Guilds of Ravnica set notes would be neato.

Ric. B. Feb 8, 2020     

After 3 years of using this app i am constantly impressed by how easy to use it is. I love the fact that i can check card rulings offline, this to me is the best feature of the app. My only feedback would be a faster update.

Gre. S. Apr 19, 2020     

the best

Bar. R. May 8, 2019     

This is probably my favorite app, period. I use it regularly, when working as a judge or as a player with my friends. Amazing work and please keep it updated, I can't live withiut it! :)

Rya. K. Jul 27, 2018     

Great app. I use this all the time to look up errata rulings while playing with friends.

Aar. Jul 7, 2018     

I want to thank you for the recent update. But the comprehensive is outdated hopefully that update comes soon. I realize the comp rules update rolled out the same day as this last update.

Pat. B. Jun 21, 2018     

Still has incorrect rulings for blood moon. I would happily turn on the ads to help support development if I felt I could rely on this for rulings. As it stands I have to use online only options

A. G. u. Apr 23, 2018     

Entire app is between 6mo and 2 years out of date.

Leo. O. Apr 20, 2018     

Modern Banlist is not updated. Pls update.

Ale. V. Aug 1, 2017     

I think it could be better if it could search by cmc.

Don. D. Jul 14, 2017     

The best thing ever

A. G. u. May 15, 2017     

One hell of a mtg app!

Rac. W. Feb 8, 2017     

It's okay, review would be amazing if the ban list was accurate. Other than that I enjoy using this at my LGS

Jac. G. Jan 24, 2017     

It's wonderful. I use this app dang near religiously. I act as a judge for local tournaments and this is an amazing tool for every situation.

Mii. Mar 23, 2017     

Great, aside from the current ban/restricted list not being up to date. As an L2, it is information needed at times, especially in Legacy and Modern events where the list is long.

Mik. R. Feb 4, 2017     

Ban list is not up to date, otherwise decent app.

VIV. Apr 3, 2017     

Absolutely crap... The worst iteration of a MTG rule book I've ever seen.. it doesn't really tell you anything except what you can do but not how it's done.. absolutely pitiful..
