# Dolphin vs SAT Math Prep

The clearest difference is in-app purchases: Dolphin at none against SAT Math Prep's 4. Dolphin also leads on ratings volume (1.3K vs 1). SAT Math Prep's advantage is review sentiment (100% vs 84%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. SAT Math Prep sells 4 one-off in-app purchases. Dolphin asks for nothing beyond the download.

SAT Math Prep holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Dolphin has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 84% of Dolphin's written reviews are positive against 100% of SAT Math Prep's.

Dolphin ships an update every 2 weeks, SAT Math Prep fortnightly. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
