Verdict

The call

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.
