ReceptionRating · Positive reviews · Number of ratings

i41CX holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: i41CX has 45 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 90% of i41CX's written reviews are positive against 100% of Super Editor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

i41CX ships an update every 5 weeks, Super Editor daily. The most recent releases landed on September 26, 2026 and September 8, 2026 respectively.
