A is free to download; Midi Studio costs $1.99 up front. A sells 4 one-off in-app purchases and Midi Studio sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

A holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 185 and 65 respectively. Written reviews complicate that: 61% of A's written reviews are positive against 64% of Midi Studio's, so the app with the better star average is not the one people write more warmly about.
