# PDF Editor vs iSign

The clearest difference is review sentiment: iSign at 100% against PDF Editor's 23%. iSign also leads on rating (5.0 vs 4.6). PDF Editor's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (331 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Editor sells 10 in-app purchases, starting at $2.99 per 7 days and iSign sells 9 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

iSign holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: PDF Editor has 331 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 23% of PDF Editor's written reviews are positive against 100% of iSign's.

PDF Editor ships an update every 4 days, iSign every 3 weeks. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
