# ICD vs ICD 10 Coding Guide

The clearest difference is monetization model: ICD at freemium against ICD 10 Coding Guide's subscription. ICD also leads on review sentiment (50% vs 17%) and iOS requirement (13.0 vs 15.0). ICD 10 Coding Guide's advantage is rating (4.4 vs 4.0) and ratings volume (167 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ICD sells 3 in-app purchases, starting at $3.49 per month and ICD 10 Coding Guide sells 1 in-app purchase, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

ICD 10 Coding Guide holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: ICD 10 Coding Guide has 167 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of ICD's written reviews are positive against 17% of ICD 10 Coding Guide's, so the app with the better star average is not the one people write more warmly about.

ICD ships an update every 14 months, ICD 10 Coding Guide every 11 months. The most recent releases landed on October 8, 2026 and October 9, 2026 respectively.
