ReceptionRating · Positive reviews · Number of ratings

Sign Documents holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Sign Documents has 152 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 22% of Sign PDF documents'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.

UpkeepUpdate frequency

Sign PDF documents ships an update every 3 weeks, Sign Documents weekly. The most recent releases landed on August 14, 2026 and September 23, 2026 respectively.
