I failed to play DoW at Origins last year and then failed again at GenCon. After hearing enough rave reviews I finally decided to buy it sight unseen a month ago.
It is great! My only regret is that I haven't gotten it on the table more in the last month. And, I guess, I also regret that the crossroads deck doesn't lend itself to being made into and app but that is rather a specific requirement for my interests. :)
I use Arkham Companion. Once we found that we never went back. It replaces most of the decks on the table. It saves so much time and space. https://play.google.com/store/apps/details?id=com.fenyx4.arkham&hl=en_US&gl=US

And there is an official iOS one.
It's called "Arkham Companion" by Fenyx Four.
Edit: Found out how to link it for Android. Not sure if it's also available in Apple.
