XP Block holds the better App Store score, 3.0 against 2.8.

Written reviews complicate that: 47% of iM.Master's written reviews are positive against 0% of XP Block's, so the app with the better star average is not the one people write more warmly about.
iM.Master ships an update every 2 months, XP Block every 4 months. The most recent releases landed on September 22, 2026 and September 16, 2026 respectively.
