Verdict
The clearest difference is in-app purchases: PlexusMD Viewer at none against OBPro Obstetric Assistant's 2. PlexusMD Viewer also leads on update cadence (every 2 days vs fortnightly). OBPro Obstetric Assistant's advantage is iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
