Verdict
The clearest difference is in-app purchases: Cortrium C3 at none against Pregnancy App's 4. Cortrium C3 also leads on iOS requirement (12.0 vs 17.0). Pregnancy App's advantage is update cadence (every 2 months vs every 11 months). On price, ads and device support there is nothing between them.
