The Three Kingdoms Guide — a deeper way to explore the Three Kingdoms. How differently do the official history — Chen Shou's Records of the Three Kingdoms (正史) — and the classic novel Romance of the Three Kingdoms (演義) tell the same events? The Three Kingdoms Guide lets you compare the lives of 164 Three Kingdoms figures — Cao Cao, Liu Bei, Guan Yu, and more — side by side, in two columns: history and legend. Explore 25 major events and 9 decisive battles, more than 300 Chinese idioms and 100 strategies born from the Romance of the Three Kingdoms, and 180 passages of original classical Chinese text — built for readers who want to read the official history and the novel together, more deeply.

Verdict
The clearest difference is price: Three Kingdoms Guide at Free against Chord's $3.99. Three Kingdoms Guide also leads on update cadence (every 4 days vs monthly). Chord's advantage is in-app purchases (none vs 1) and device support (5 vs 1). On ads there is nothing between them.
