Verdict
The clearest difference is monetization model: Zenith Agent at freemium against ChatLLM's subscription. Zenith Agent also leads on review sentiment (100% vs 64%). ChatLLM's advantage is ratings volume (3.8K vs 2) and update cadence (every 4 days vs fortnightly). On price, rating, ads 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. ChatLLM sells 3 in-app purchases, starting at $9.99 per month and Zenith Agent sells 2 in-app purchases, starting at $29.99 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 — 4.9 for ChatLLM against 5.0 for Zenith Agent. That said, the two scores are not equally well evidenced: ChatLLM has 3.8K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 64% of ChatLLM's written reviews are positive against 100% of Zenith Agent's.
ChatLLM ships an update every 4 days, Zenith Agent fortnightly. The most recent releases landed on October 30, 2026 and October 14, 2026 respectively.
