Both are free to download. Chainlock VPN sells 3 in-app purchases, starting at $9.99 per 7 days and Duality sells 7 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Chainlock VPN holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Chainlock VPN has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 91% of Chainlock VPN's written reviews are positive against 100% of Duality's, so the app with the better star average is not the one people write more warmly about.
