# ICD 9 vs ICD

The clearest difference is in-app purchases: ICD 9 at none against ICD's 4. ICD 9 also leads on ads (none vs shown) and iOS requirement (12.3 vs 18.6). ICD's advantage is update cadence (every 10 days vs every 5 weeks). On price, review sentiment and device support there is nothing between them.

Both are free to download. ICD sells 4 in-app purchases, starting at $4.99 per month. ICD 9 asks for nothing beyond the download.

ICD 9 ships an update every 5 weeks, ICD every 10 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
