Both are free to download. MixMaster A/B sells 1 one-off in-app purchase and jAmpler sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
jAmpler holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 4 and 6 respectively. Written reviews complicate that: 100% of MixMaster A/B's written reviews are positive against 60% of jAmpler's, so the app with the better star average is not the one people write more warmly about.
