# Pythagoras HD vs SAT Math

The clearest difference is price: SAT Math at Free against Pythagoras HD's $0.99. SAT Math also leads on rating (4.8 vs 1.0) and update cadence (every 10 months vs every 24 months). Pythagoras HD's advantage is in-app purchases (none vs 1) and iOS requirement (12.0 vs 15.0). On ads there is nothing between them.

SAT Math is free to download; Pythagoras HD costs $0.99 up front. SAT Math sells 1 one-off in-app purchase. Pythagoras HD asks for nothing beyond the download.

SAT Math holds the better App Store score, 4.8 against 1.0. 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.

Pythagoras HD ships an update every 24 months, SAT Math every 10 months. The most recent releases landed on June 5, 2026 and June 2, 2026 respectively.
