# My Lisp vs OCaml

The clearest difference is price: OCaml at Free against My Lisp's $3.99. OCaml also leads on rating (4.6 vs 4.1) and iOS requirement (15.0 vs 18.0). My Lisp's advantage is in-app purchases (none vs 3) and chart position (#87 vs unranked). On review sentiment, ratings volume, update cadence and ads there is nothing between them.

OCaml is free to download; My Lisp costs $3.99 up front. OCaml sells 3 one-off in-app purchases. My Lisp asks for nothing beyond the download.

OCaml holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 17 and 17 respectively. Written reviews complicate that: 69% of My Lisp's written reviews are positive against 64% of OCaml's, so the app with the better star average is not the one people write more warmly about.

My Lisp ships an update every 6 weeks, OCaml monthly. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
