# Mosa AI vs SonnetAI

The clearest difference is rating: SonnetAI at 5.0 against Mosa AI's 4.5. Mosa AI's advantage is update cadence (every 6 days vs every 9 months) and ratings volume (374 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mosa AI sells 8 in-app purchases, starting at $6.99 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 4.5. That said, the two scores are not equally well evidenced: Mosa AI has 374 ratings behind it against 2, so its average is the more settled of the two.

Mosa AI ships an update every 6 days, SonnetAI every 9 months. The most recent releases landed on October 20, 2026 and October 14, 2026 respectively.
