# Knack vs Mirror Browser

The clearest difference is review sentiment: Knack at 100% against Mirror Browser's 50%. Knack also leads on iOS requirement (16.0 vs 18.0). Mirror Browser's advantage is update cadence (every 9 days vs every 2 months) and rating (5.0 vs 4.8). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Mirror Browser holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 3 respectively. Written reviews complicate that: 100% of Knack's written reviews are positive against 50% of Mirror Browser's, so the app with the better star average is not the one people write more warmly about.
