# OpenCat vs ChatMate+

The clearest difference is rating: OpenCat at 4.6 against ChatMate+'s 4.0. OpenCat also leads on ratings volume (851 vs 1). ChatMate+'s advantage is review sentiment (100% vs 65%) and in-app purchases (none vs 4). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. OpenCat sells 4 in-app purchases, starting at $3.99 per month. ChatMate+ asks for nothing beyond the download.

OpenCat holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: OpenCat has 851 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 65% of OpenCat's written reviews are positive against 100% of ChatMate+'s, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
