# ReasonML vs Code Editor

The clearest difference is review sentiment: ReasonML at 100% against Code Editor's 54%. ReasonML also leads on rating (5.0 vs 3.2) and in-app purchases (none vs 1). Code Editor's advantage is ratings volume (43 vs 3) and chart position (#85 vs unranked). On price and device support there is nothing between them.

Both are free to download. Code Editor sells 1 one-off in-app purchase. ReasonML asks for nothing beyond the download.

ReasonML holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Code Editor has 43 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of ReasonML's written reviews are positive against 54% of Code Editor's.

ReasonML ships an update every 2 days, Code Editor every 5 weeks. The most recent releases landed on September 20, 2026 and October 7, 2026 respectively.
