# Domain Check vs DocuScan

The clearest difference is update cadence: DocuScan at every 4 days against Domain Check's every 14 months. DocuScan also leads on iOS requirement (15 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Domain Check sells 1 one-off in-app purchase and DocuScan sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Domain Check ships an update every 14 months, DocuScan every 4 days. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
