Verdict

The call

The clearest difference is review sentiment: Medical Dictionary by Farlex at 93% against ICD's 50%. Medical Dictionary by Farlex also leads on rating (4.8 vs 4.0) and update cadence (every 2 months vs every 14 months). ICD's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.
