That said, the two scores are not equally well evidenced: Voice Synth Modular has 3K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 64% of Autoharp's written reviews are positive against 41% of Voice Synth Modular's, so the app with the better star average is not the one people write more warmly about.
