Verdict
The clearest difference is in-app purchases: My Kitty Calculator at none against PrintDiary's 1. My Kitty Calculator also leads on iOS requirement (15.6 vs 18.0). PrintDiary's advantage is update cadence (every 2 weeks vs every 23 months). On price, ads and device support there is nothing between them.
