Verdict

The call

The clearest difference is monetization model: 完美日历 at free against Tide Chart Master's subscription. 完美日历 also leads on update cadence (every 3 weeks vs every 4 months). Tide Chart Master's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
