# SAT Math vs Terpsi

The clearest difference is update cadence: Terpsi at every 2 weeks against SAT Math's every 8 months. SAT Math's advantage is iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SAT Math sells 1 one-off in-app purchase and Terpsi sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SAT Math ships an update every 8 months, Terpsi every 2 weeks. The most recent releases landed on September 17, 2026 and October 28, 2026 respectively.
