# RTA Audio vs KRK Audio Tools

The clearest difference is rating: KRK Audio Tools at 4.1 against RTA Audio's 3.5. KRK Audio Tools also leads on in-app purchases (none vs 1) and iOS requirement (9.3 vs 15.6). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. RTA Audio sells 1 one-off in-app purchase. KRK Audio Tools asks for nothing beyond the download.

KRK Audio Tools holds the better App Store score, 4.1 against 3.5. Both are backed by a comparable volume of ratings — 32 and 40 respectively. Written reviews complicate that: 59% of RTA Audio's written reviews are positive against 54% of KRK Audio Tools's, so the app with the better star average is not the one people write more warmly about.
