Verdict
The clearest difference is in-app purchases: Physics Balls at none against Brain Dots's 10. Physics Balls also leads on review sentiment (79% vs 50%) and iOS requirement (11.0 vs 15.6). Brain Dots's advantage is rating (4.4 vs 4.0) and ratings volume (8.2K vs 56). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Brain Dots sells 10 one-off in-app purchases. Physics Balls asks for nothing beyond the download.
Brain Dots holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Brain Dots has 8.2K ratings behind it against 56, so its average is the more settled of the two. Written reviews complicate that: 79% of Physics Balls's written reviews are positive against 50% of Brain Dots's, so the app with the better star average is not the one people write more warmly about.
Physics Balls ships an update monthly, Brain Dots every 3 weeks. Both last shipped on October 26, 2026.
