ReceptionRating · Positive reviews · Number of ratings

CodeMaster holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: CodeMaster has 140 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 44% of CodeMaster's written reviews are positive against 54% of Power JSON Editor Mobile's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CodeMaster ships an update monthly, Power JSON Editor Mobile every 11 days. The most recent releases landed on October 10, 2026 and September 27, 2026 respectively.
