# Bernard AI vs Document Signer

The clearest difference is ratings volume: Bernard AI at 713 against Document Signer's 26. Document Signer's advantage is review sentiment (75% vs 64%) and iOS requirement (15.1 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Bernard AI sells 9 in-app purchases, starting at $2.99 per 7 days and Document Signer sells 4 in-app purchases, starting at $4.99 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 — 4.6 for Bernard AI against 4.7 for Document Signer. That said, the two scores are not equally well evidenced: Bernard AI has 713 ratings behind it against 26, so its average is the more settled of the two. Written reviews are what separate them: 64% of Bernard AI's written reviews are positive against 75% of Document Signer's.
