Verdict

The call

The clearest difference is in-app purchases: 年号電卓Plus at none against OpenReport's 1. 年号電卓Plus also leads on ads (none vs shown) and review sentiment (38% vs 29%). OpenReport's advantage is update cadence (every 3 weeks vs every 6 weeks) and iOS requirement (13.0 vs 17.6). On price and device support there is nothing between them.
