Verdict

The call

The clearest difference is in-app purchases: MedicalData at none against Conversion Calculator Plus's 1. MedicalData also leads on ads (none vs shown) and review sentiment (100% vs 70%). Conversion Calculator Plus's advantage is ratings volume (15K vs 1) and update cadence (every 2 days vs weekly). On price, device support and iOS requirement there is nothing between them.
