Both are free to download. JSBox sells 2 in-app purchases, starting at $7.99 per year and CodeMaster sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

CodeMaster holds the better App Store score, 4.6 against 4.0. Both are backed by a comparable volume of ratings — 85 and 139 respectively. Written reviews complicate that: 50% of JSBox's written reviews are positive against 44% of CodeMaster's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

JSBox ships an update fortnightly, CodeMaster monthly. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
