# My Lisp vs IconGPT

The clearest difference is price: IconGPT at Free against My Lisp's $3.99. IconGPT also leads on review sentiment (100% vs 69%) and update cadence (every 3 days vs every 6 weeks). My Lisp's advantage is in-app purchases (none vs 2) and ratings volume (18 vs 1). On rating, ads, device support and iOS requirement there is nothing between them.

IconGPT is free to download; My Lisp costs $3.99 up front. IconGPT sells 2 one-off in-app purchases. My Lisp asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.1 for My Lisp against 4.0 for IconGPT. That said, the two scores are not equally well evidenced: My Lisp has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 69% of My Lisp's written reviews are positive against 100% of IconGPT's.

My Lisp ships an update every 6 weeks, IconGPT every 3 days. The most recent releases landed on November 1, 2026 and October 9, 2026 respectively.
