# ChatGPT vs Google Gemini

The clearest difference is ads: Google Gemini at none against ChatGPT's shown. ChatGPT's advantage is ratings volume (11M vs 2.3M) and chart position (#1 vs #3). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. ChatGPT sells 8 in-app purchases, starting at $8.00 per month and Google Gemini sells 18 in-app purchases, starting at $1.99 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 — 4.8 for ChatGPT against 4.7 for Google Gemini. Both are backed by a comparable volume of ratings — 11M and 2.3M respectively. Written reviews are what separate them: 70% of ChatGPT's written reviews are positive against 67% of Google Gemini's.

ChatGPT ships an update weekly, Google Gemini every 5 days. Both last shipped on September 25, 2026.
