I have 2 of Robert Camps books, Love Cards, and Cards of Destiny, I haven't tried app yet, just downloaded it. I absolutely love his books and have learned so much from them. I do charts all the time, like if I meet someone new, and you can also look up your friends relationships, and family as well!! Thank you so much for making this app, I'm sure it's a good one. I am the 4 of Diamonds, I have already met one of my Karma Cards, and one of the other. I wonder how often people come in your life like that!!! I'm so thrilled to get into this app cause I bet that it is fabulous!!
