# JSBox vs CodeMaster

The clearest difference is rating: CodeMaster at 4.6 against JSBox's 4.0. JSBox's advantage is monetization model (free with in-app purchases vs subscription) and chart position (#73 vs unranked). On price, review sentiment, ratings volume and update cadence there is nothing between them.

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.

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.

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