Verdict

The call

The clearest difference is in-app purchases: X at none against AMBOSS Medical Knowledge's 1. X also leads on ads (none vs shown) and update cadence (every 8 days vs monthly). AMBOSS Medical Knowledge's advantage is ratings volume (14K vs 1) and chart position (#29 vs unranked). On price, rating, device support and iOS requirement there is nothing between them.
