# Smart Fax vs Esign

The clearest difference is update cadence: Esign at every 2 weeks against Smart Fax's every 6 weeks. Smart Fax's advantage is review sentiment (62% vs 50%) and ratings volume (192 vs 24). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Smart Fax sells 4 in-app purchases, starting at $8.99 per 7 days and Esign sells 1 in-app purchase, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.1 for Smart Fax against 4.3 for Esign. That said, the two scores are not equally well evidenced: Smart Fax has 192 ratings behind it against 24, so its average is the more settled of the two. Written reviews are what separate them: 62% of Smart Fax's written reviews are positive against 50% of Esign's.

Smart Fax ships an update every 6 weeks, Esign every 2 weeks. The most recent releases landed on November 6, 2026 and October 30, 2026 respectively.
