# Smart Printer vs iSign

The clearest difference is rating: iSign at 5.0 against Smart Printer's 4.3. Smart Printer's advantage is ratings volume (87 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Smart Printer sells 7 in-app purchases, starting at $3.99 per 7 days and iSign sells 4 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 4.3. That said, the two scores are not equally well evidenced: Smart Printer has 87 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Smart Printer ships an update every 3 weeks, iSign fortnightly. The most recent releases landed on October 6, 2026 and September 29, 2026 respectively.
