Verdict
The clearest difference is ads: Castleridge Vet at none against Canada Post's shown. Castleridge Vet also leads on iOS requirement (11.0 vs 16.0). Canada Post's advantage is update cadence (every 3 weeks vs every 13 months). On price, in-app purchases and device support there is nothing between them.
