# Atoms HD vs Physics 2d

The clearest difference is in-app purchases: Physics 2d at none against Atoms HD's 7. Physics 2d also leads on rating (4.0 vs 3.6) and update cadence (every 13 months vs every 64 months). Atoms HD's advantage is ratings volume (19 vs 3) and iOS requirement (12.0 vs 16.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Atoms HD sells 7 one-off in-app purchases. Physics 2d asks for nothing beyond the download.

Physics 2d holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: Atoms HD has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 54% of Atoms HD's written reviews are positive against 50% of Physics 2d's, so the app with the better star average is not the one people write more warmly about.

Atoms HD ships an update every 64 months, Physics 2d every 13 months. The most recent releases landed on October 16, 2026 and September 23, 2026 respectively.
