Verdict
The clearest difference is update cadence: Sider at every 11 days against SonnetAI's every 9 months. Sider also leads on ratings volume (4.3K vs 2). SonnetAI's advantage is rating (5.0 vs 4.7) and iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and monetization model 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. Sider sells 10 in-app purchases, starting at $9.99 per month 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: Sider has 4.3K ratings behind it against 2, so its average is the more settled of the two.
Sider ships an update every 11 days, SonnetAI every 9 months. The most recent releases landed on November 7, 2026 and October 30, 2026 respectively.
