# Duality vs KeenVPN

The clearest difference is rating: KeenVPN at 5.0 against Duality's 3.7. KeenVPN also leads on update cadence (every 3 days vs fortnightly) and ratings volume (15 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Duality sells 7 in-app purchases, starting at $5.99 per month and KeenVPN sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

KeenVPN holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: KeenVPN has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Duality ships an update fortnightly, KeenVPN every 3 days. Both last shipped on November 5, 2026.
