Verdict
The clearest difference is review sentiment: eSign App at 85% against pdfFiller's 20%. eSign App also leads on rating (4.8 vs 4.4). pdfFiller's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (8.5K vs 1.5K). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. pdfFiller sells 10 in-app purchases, starting at $19.99 per month and eSign App sells 9 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
eSign App holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: pdfFiller has 8.5K ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews point the same way: 20% of pdfFiller's written reviews are positive against 85% of eSign App's.
pdfFiller ships an update fortnightly, eSign App every 3 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
