# PDFDarkMode vs AutoDoc Scan

PDFDarkMode and AutoDoc Scan are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. PDFDarkMode sells 5 one-off in-app purchases and AutoDoc Scan sells 2 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

PDFDarkMode ships an update every 4 days, AutoDoc Scan every 3 days. The most recent releases landed on October 24, 2026 and October 7, 2026 respectively.
