# ICD vs Medical Dictionary by Farlex

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.

Both are free to download. ICD sells 3 in-app purchases, starting at $3.49 per month and Medical Dictionary by Farlex sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Medical Dictionary by Farlex has 7K ratings behind it against 4, so its average is the more settled of the two.
