# Modulo vs PDF转换编辑

The clearest difference is in-app purchases: PDF转换编辑 at none against Modulo's 1. PDF转换编辑 also leads on iOS requirement (12.0 vs 26.0). Modulo's advantage is ads (none vs shown) and update cadence (fortnightly vs every 6 weeks). On price and device support there is nothing between them.

Both are free to download. Modulo sells 1 one-off in-app purchase. PDF转换编辑 asks for nothing beyond the download.

Modulo ships an update fortnightly, PDF转换编辑 every 6 weeks. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
