# ChatPlus vs SonnetAI

The clearest difference is update cadence: ChatPlus at every 2 weeks against SonnetAI's every 9 months. ChatPlus also leads on ratings volume (2.1K vs 2). SonnetAI's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ChatPlus sells 11 in-app purchases, starting at $7.99 per 7 days and SonnetAI sells 4 in-app purchases, starting at $25.00 per month. Whichever you choose, the download price is not the number that matters.

SonnetAI holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ChatPlus has 2.1K ratings behind it against 2, so its average is the more settled of the two.

ChatPlus ships an update every 2 weeks, SonnetAI every 9 months. The most recent releases landed on October 21, 2026 and October 14, 2026 respectively.
