ReceptionRating · Positive reviews · Number of ratings

Speech Central holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Speech Central has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 69% of Speech Central's written reviews are positive against 100% of ProveIt AI's, so the app with the better star average is not the one people write more warmly about.
