CORE Open House holds the better App Store score, 3.7 against 3.5. That said, the two scores are not equally well evidenced: CORE Open House has 58 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 48% of CORE Open House's written reviews are positive against 60% of REDX CallerID's, so the app with the better star average is not the one people write more warmly about.
