# ZipSign vs Sign Documents

The clearest difference is review sentiment: ZipSign at 96% against Sign Documents's 0%. ZipSign also leads on ratings volume (56 vs 6). Sign Documents's advantage is rating (5.0 vs 4.6) and iOS requirement (15.0 vs 18.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ZipSign sells 8 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.

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 56 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.

ZipSign ships an update every 4 days, Sign Documents weekly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
