CORE Open House holds the better App Store score, 3.7 against 3.5.

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.
CORE Open House ships an update every 6 weeks, REDX CallerID every 5 weeks. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
