Verdict
The clearest difference is in-app purchases: PetPlan at none against May Calendar's 1. PetPlan also leads on ads (none vs shown) and update cadence (every 6 days vs every 3 weeks). May Calendar's advantage is iOS requirement (16.6 vs 26.2). On price and device support there is nothing between them.
