# ChatMCP vs HemiSync

ChatMCP and HemiSync both sit at 4.3 stars, but that hides the real split: 100% of HemiSync's written reviews are positive against 58% of ChatMCP's. ChatMCP's advantage is update cadence (every 6 days vs every 5 weeks) and ratings volume (63 vs 9). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. ChatMCP sells 3 in-app purchases, starting at $19.99 per month and HemiSync sells 1 in-app purchase, starting at $0.99 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 — 4.3 for ChatMCP against 4.2 for HemiSync. That said, the two scores are not equally well evidenced: ChatMCP has 63 ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 58% of ChatMCP's written reviews are positive against 100% of HemiSync's.

ChatMCP ships an update every 6 days, HemiSync every 5 weeks. The most recent releases landed on July 5, 2026 and August 29, 2026 respectively.
