Verdict

The call

The clearest difference is in-app purchases: Parallel Chronology at none against 世界史年表's 1. Parallel Chronology also leads on iOS requirement (15.0 vs 17.0). 世界史年表's advantage is update cadence (fortnightly vs every 9 months). On price, ads and device support there is nothing between them.
