Verdict

The call

The clearest difference is rating: 签字宝 at 5.0 against Sign Documents's 4.5. 签字宝 also leads on update cadence (every 3 weeks vs every 6 weeks) and iOS requirement (13.0 vs 15.0). Sign Documents's advantage is ratings volume (68 vs 1) and review sentiment (88% vs 67%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 签字宝 sells 3 in-app purchases, starting at $4.99 per month and Sign Documents sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

签字宝 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sign Documents has 68 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of 签字宝's written reviews are positive against 88% of Sign Documents's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

签字宝 ships an update every 3 weeks, Sign Documents every 6 weeks. Both last shipped on October 30, 2026.
