What's New in Jade Codex

2.1

October 10, 2026

Version 2.1 • Find a good day. Choose what you're planning (a wedding, a move, opening a business, a haircut) and see the coming days the almanac favors for it, each with its reason. Premium looks 90 days ahead and ranks the days for your chart. • A morning almanac. One notification with the day's 宜 opens today's page. With Premium and your chart, it names the one that suits you, and why. • Jade Codex now speaks Español and 繁體中文, alongside English and 简体中文: the almanac, your chart, the dream dictionary and the written readings. • Easier to read: a new type scale, stronger contrast, and text that grows to the largest accessibility sizes. • Your first run shows today's almanac read for you, and Today opens on a single "for you" card you can share. • Premium works on every iPhone running iOS 26. The ranking, the daily breakdown and your chart are computed on your iPhone; written readings use Apple Intelligence where your iPhone supports it. • Dream symbols on every iPhone: describe a dream in your own words and see the symbols it matches. • The widget and notifications open today's almanac, and Your Book opens on My Chart. • Corrected: hexagrams containing the trigrams 震, 艮, 巽 or 兌 are now drawn and named correctly. Readings you saved before stay as recorded.
