# CodeMaster vs Power JSON Editor Mobile

The clearest difference is rating: CodeMaster at 4.6 against Power JSON Editor Mobile's 3.2. CodeMaster also leads on ratings volume (140 vs 10). Power JSON Editor Mobile's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 11 days vs monthly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. CodeMaster sells 3 in-app purchases, starting at $1.99 per 7 days and Power JSON Editor Mobile sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

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.

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.
