# ICD vs ICD 10 Coding Guide

The clearest difference is rating: ICD at 4.8 against ICD 10 Coding Guide's 4.4. ICD also leads on monetization model (paid vs subscription) and update cadence (every 3 months vs every 11 months). ICD 10 Coding Guide's advantage is ratings volume (167 vs 11). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ICD sells 1 one-off in-app purchase 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 holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: ICD 10 Coding Guide has 167 ratings behind it against 11, so its average is the more settled of the two.

ICD ships an update every 3 months, ICD 10 Coding Guide every 11 months. The most recent releases landed on October 15, 2026 and October 9, 2026 respectively.
