# Parallel Chronology vs 世界史年表

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.

Both are free to download. 世界史年表 sells 1 one-off in-app purchase. Parallel Chronology asks for nothing beyond the download.

Parallel Chronology ships an update every 9 months, 世界史年表 fortnightly. Both last shipped on November 7, 2026.
