# ICD vs ICD 10 Coding Guide

The clearest difference is in-app purchases: ICD at none against ICD 10 Coding Guide's 1. ICD also leads on update cadence (fortnightly vs every 11 months) and iOS requirement (8.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. ICD 10 Coding Guide sells 1 in-app purchase, starting at $9.99 per year. ICD asks for nothing beyond the download.

ICD ships an update fortnightly, ICD 10 Coding Guide every 11 months. The most recent releases landed on September 30, 2026 and October 9, 2026 respectively.
