Both are free to download. ZipSign sells 10 in-app purchases, starting at $9.99 per 7 days and Sign Documents sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Sign Documents holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ZipSign has 57 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 96% of ZipSign'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

ZipSign ships an update every 4 days, Sign Documents every 2 weeks. The most recent releases landed on October 18, 2026 and October 19, 2026 respectively.
