# SAT Math vs One

The clearest difference is in-app purchases: One at none against SAT Math's 1. One also leads on update cadence (every 2 days vs every 10 months). On price, ads, device support and iOS requirement there is nothing between them.

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

SAT Math ships an update every 10 months, One every 2 days. The most recent releases landed on September 23, 2026 and October 2, 2026 respectively.
