Verdict
The clearest difference is ads: Grok at none against ChatGPT's shown. Grok also leads on monetization model (free vs free with in-app purchases) and update cadence (every 2 days vs every 6 days). ChatGPT's advantage is ratings volume (12M vs 1.6M) and chart position (#1 vs #4). On price, rating, review sentiment and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ChatGPT sells 9 in-app purchases, starting at $8.00 per month and Grok sells 11 in-app purchases, starting at $10.00 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 — 4.8 for ChatGPT against 4.9 for Grok. That said, the two scores are not equally well evidenced: ChatGPT has 12M ratings behind it against 1.6M, so its average is the more settled of the two. Written reviews split almost evenly too, at 71% and 72% positive.
ChatGPT ships an update every 6 days, Grok every 2 days. Both last shipped on October 31, 2026.
