Verdict
The clearest difference is price: I CHING 1 at Free against Yi Jing's $4.99. I CHING 1 also leads on in-app purchases (none vs 10) and update cadence (every 5 weeks vs every 4 months). Yi Jing's advantage is ratings volume (917 vs 6) and chart position (#80 vs unranked). On rating, ads and device support there is nothing between them.
