# I Ching Oracle vs 紫微通書

I Ching Oracle and 紫微通書 both sit at 4.8 stars, but that hides the real split: 100% of I Ching Oracle's written reviews are positive against 50% of 紫微通書's. I Ching Oracle also leads on in-app purchases (none vs 5) and ratings volume (99 vs 4). 紫微通書's advantage is iOS requirement (12.0 vs 15.2). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. 紫微通書 sells 5 one-off in-app purchases. I Ching Oracle asks for nothing beyond the download.

紫微通書 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: I Ching Oracle has 99 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of I Ching Oracle's written reviews are positive against 50% of 紫微通書's, so the app with the better star average is not the one people write more warmly about.

I Ching Oracle ships an update fortnightly, 紫微通書 every 4 weeks. The most recent releases landed on October 21, 2026 and October 27, 2026 respectively.
