# ChatOn AI vs ChatGPT

The clearest difference is ratings volume: ChatGPT at 11M against ChatOn AI's 285K. ChatGPT also leads on chart position (#1 vs #18). ChatOn AI's advantage is review sentiment (79% vs 70%) and iOS requirement (16.0 vs 18.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. ChatOn AI sells 9 in-app purchases, starting at $6.99 per 7 days and ChatGPT sells 8 in-app purchases, starting at $8.00 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for ChatOn AI against 4.8 for ChatGPT. That said, the two scores are not equally well evidenced: ChatGPT has 11M ratings behind it against 285K, so its average is the more settled of the two. Written reviews are what separate them: 79% of ChatOn AI's written reviews are positive against 70% of ChatGPT's.

ChatOn AI ships an update every 11 days, ChatGPT weekly. Both last shipped on September 24, 2026.
