# SimplePhysics vs Pocket Galaxy

The clearest difference is in-app purchases: Pocket Galaxy at none against SimplePhysics's 2. Pocket Galaxy also leads on rating (4.8 vs 4.5) and ratings volume (10K vs 242). SimplePhysics's advantage is update cadence (every 3 weeks vs every 2 months) and price ($0.99 vs $3.99). On ads and device support there is nothing between them.

SimplePhysics costs $0.99 and Pocket Galaxy $3.99 up front. SimplePhysics sells 2 one-off in-app purchases. Pocket Galaxy asks for nothing beyond the download.

Pocket Galaxy holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Pocket Galaxy has 10K ratings behind it against 242, so its average is the more settled of the two. Written reviews point the same way: 85% of SimplePhysics's written reviews are positive against 95% of Pocket Galaxy's.

SimplePhysics ships an update every 3 weeks, Pocket Galaxy every 2 months. Both last shipped on October 18, 2026.
