# ICF Codes vs ICD

The clearest difference is review sentiment: ICD at 100% against ICF Codes's 56%. ICD also leads on in-app purchases (none vs 1) and update cadence (every 4 months vs every 9 months). ICF Codes's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.6). On price and device support there is nothing between them.

Both are free to download. ICF Codes sells 1 one-off in-app purchase. ICD asks for nothing beyond the download.

ICF Codes ships an update every 9 months, ICD every 4 months. The most recent releases landed on October 8, 2026 and October 27, 2026 respectively.
