The call

The clearest difference is in-app purchases: About Herbs at none against VisualDx's 11. About Herbs also leads on iOS requirement (12.0 vs 16.4). VisualDx's advantage is update cadence (fortnightly vs every 14 months) and rating (4.4 vs 4.0). On price, ratings volume, ads and device support there is nothing between them.
