Well, it would be a good app, if it contained ruling for all cards.. But most of the recent cards don't have rulings in this app, only the effect is described (which is kinda useless). Also, the view image feature is broken (I don't really mind that part).

Ya need to update the card list

A. G. u. Apr 8, 2019

I know the card database was not updated constantly but now it just doesn't even work anymore. App was crashing a lot so I tried uninstalling it and installing it again and it doesnt even open now. Really bad.

The app is good at rulings for certain cards, but not all cards have rulings explained, so that's why I can't give it more than a 4

For over a month now, app keeps crashing on startup. Uninstalled and reinstalled multiple times to no avail. Please fix. Loved the app when it worked

Great for those times when you're not sure on ruling. Simple and easy to use. Only issue is you have to go into settings and get the update. App starts as an older version. Would be nice if it were the recent version when installed. A duelests best friend.

This app is so cool now I know number 1000's effect

A. G. u. Dec 2, 2015

Good app, handy, would be nice if it had a card-type search (level, type, etc) would also be nice if it had the rules of the game as well. Also, now it won't even load

This app constantly shuts down but when it works its proper

A. G. u. Apr 9, 2018

This app does not show all the cards

A. G. u. Mar 25, 2018

Database needs updating but wont update

A. G. u. Feb 18, 2018

Will not open

A. G. u. Feb 6, 2016

Also, if I put in "winged dragon", search should bring up cards with that combination anywhere in their name.

A. G. u. Oct 3, 2015

It won't let me search cards, there's only a clear button.

A. G. u. May 31, 2015

It's a great app to solve the ruling issues but it would be awesome if you could have a card search system that shows different aspects of the cards, like card type, level/rank etc.

A. G. u. Jun 29, 2015

It doesn't have spell/trap card ruling would b nice to see in a update if possable

A. G. u. May 30, 2015

Just needs a few Lil things and it'll be perfect this new update jus made the app perfect lol

A. G. u. Jun 10, 2015

Its great

A. G. u. Oct 23, 2014

Amazing app. Auto updates are convenient and it even works (minus the updating part) when offline. It's something every judge should have.

A. G. u. Apr 10, 2015

Great app! But whenever I go to get updates it says: error 404 not found
