# DocuShield vs Lisa Chat

The clearest difference is ads: DocuShield at none against Lisa Chat's shown. DocuShield also leads on review sentiment (83% vs 50%) and update cadence (every 2 weeks vs monthly). Lisa Chat's advantage is ratings volume (891 vs 37). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. DocuShield sells 1 in-app purchase, starting at $12.99 per 7 days and Lisa Chat sells 4 in-app purchases, starting at $5.99 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 DocuShield against 4.4 for Lisa Chat. That said, the two scores are not equally well evidenced: Lisa Chat has 891 ratings behind it against 37, so its average is the more settled of the two. Written reviews are what separate them: 83% of DocuShield's written reviews are positive against 50% of Lisa Chat's.

DocuShield ships an update every 2 weeks, Lisa Chat monthly. Both last shipped on November 3, 2026.
