Verdict
The clearest difference is in-app purchases: OEI Sim at none against VitalCore's 1. OEI Sim also leads on ads (none vs shown) and ratings volume (4 vs 1). VitalCore's advantage is update cadence (every 2 days vs every 3 months) and device support (3 vs 1). On price, rating and iOS requirement there is nothing between them.
