# SAT Math vs Onsen SAT

The clearest difference is in-app purchases: Onsen SAT at none against SAT Math's 1. Onsen SAT also leads on update cadence (fortnightly vs every 10 months) and rating (5.0 vs 4.8). SAT Math's advantage is ratings volume (5 vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. SAT Math sells 1 one-off in-app purchase. Onsen SAT asks for nothing beyond the download.

Onsen SAT holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: SAT Math has 5 ratings behind it against 1, so its average is the more settled of the two.

SAT Math ships an update every 10 months, Onsen SAT fortnightly. The most recent releases landed on September 30, 2026 and September 15, 2026 respectively.
