For years the #1 I Ching app in the world, and perhaps the most elegant, distilled version of the I Ching there is. For centuries, the Book of Changes has been consulted for sage advice at life's turning points. When its wisdom is sought with sincerity and sensitivity, this ancient Chinese oracle will promote success and good fortune and impart balance and perspective to your life. Its lasting popularity lies in the profound lessons it teaches about how reliance on one's higher qualities leads to life's greatest rewards: well-being, understanding, and peace of mind. Now available as an elegantly designed and easy to use iOS app, it is both highly accessible to new users and a revelation to those long familiar with the text. Throw your own coins, or let the app cast for you, and make the wisdom of the sages your own. This lite version contains the I Ching consulting tool and complete odd-numbered passages. Additional content and emailing feature is available through an In App Purchase. Brian Browne Walker is the author of celebrated contemporary translations of the I Ching, Tao te Ching, Hua hu Ching, and Art of War which are published by Harper and St. Martin's Press and translated into over a dozen languages around the world. His "I Ching, or Book of Changes", long beloved for its clarity and accessibility, has received five star reviews on Amazon consistently for over a decade.

Verdict
The clearest difference is in-app purchases: Retro Library at none against I Ching Lite's 2. I Ching Lite's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 26.0). On price and ads there is nothing between them.
