I do love my Fool's Dog apps. At first I wasn't sure how I'd feel about not having the cards in my hands, but I realize, my cell phone is empowered by my touch, its constant presence in my life, with my personal energies, and it's around me more often than my cards. LOL. This helped me get past any initial, and long erased, concern for not having the physical cards present. The phone is physical, the cards are symbols, energy, light--having them in any form can result in reliable readings. Sometimes more reliable, I find.
I love that they have one of my all-time favorite decks, The Prairie Tarot, as an option! I also use the Witches Tarot (Dugan and Evans), the Classic 1910 Tarot, and their Dondorf Lenormand daily.
I hope to see more Lenormand and oracle decks.
