# VisualDx vs Rabies

The clearest difference is in-app purchases: Rabies at none against VisualDx's 10. Rabies also leads on iOS requirement (12.0 vs 16.4). VisualDx's advantage is update cadence (fortnightly vs every 30 months) and chart position (#15 vs unranked). On price, ads and device support there is nothing between them.

Both are free to download. VisualDx sells 10 in-app purchases, starting at $39.99 per month. Rabies asks for nothing beyond the download.

VisualDx ships an update fortnightly, Rabies every 30 months. The most recent releases landed on November 13, 2026 and November 6, 2026 respectively.
