Verdict
The clearest difference is review sentiment: VisualDx at 84% against STAT!Ref's 36%. VisualDx also leads on rating (4.4 vs 2.8) and update cadence (fortnightly vs every 3 months). STAT!Ref's advantage is in-app purchases (none vs 11). On price, ads, device support and iOS requirement there is nothing between them.
