Verdict
The clearest difference is monetization model: SAT® at free against Dolphin's free with in-app purchases. SAT® also leads on iOS requirement (9.0 vs 16.0). Dolphin's advantage is update cadence (every 2 weeks vs every 2 months). On price, rating, review sentiment and ratings volume there is nothing between them.
