# ReasonML vs LispPad Go

The clearest difference is update cadence: ReasonML at every 2 days against LispPad Go's every 2 months. ReasonML also leads on iOS requirement (13.4 vs 17.6). LispPad Go's advantage is ratings volume (37 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 5.0 for ReasonML against 4.9 for LispPad Go. That said, the two scores are not equally well evidenced: LispPad Go has 37 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 100% of ReasonML's written reviews are positive against 96% of LispPad Go's.

ReasonML ships an update every 2 days, LispPad Go every 2 months. Both last shipped on September 20, 2026.
