★★★★★ The Best I Ching app on Android. I’ve tried them all, but they all had drawbacks – this one is different. No more rifling through a pile of books to compare translations. Stores all my questions and allows me to search for them, and has a unique dynamics function that allows you to track the energy of your situation as it changes. My only gripe is that it can be quite expensive by the time you add up all the books to purchase, but there are cheaper ones available to get you started. Love it!

★★★★★ This App has always answered my comments and queries discretely, genuinely, anonymously, honestly and openly, and with fond affection, utterly respectfully, yet without a doubt, verifiably accurately! Spirit, via this app, has been a shockingly wonderful mentor when (and I always do except maybe once or twice out of 2000+ divinations) I’ve thought what I meant, meant what I’ve thought, and simultaneously written or silently asked or commented what I’ve thought to the Universe. Thank you!!!
