Both are free to download. SignPDF sells 3 one-off in-app purchases and Sign Documents sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Sign Documents holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 105 and 39 respectively. Written reviews complicate that: 85% of SignPDF's written reviews are positive against 0% of Sign Documents's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
