# Physics Lab AR vs gravity detector

The clearest difference is in-app purchases: gravity detector at none against Physics Lab AR's 7. gravity detector also leads on rating (5.0 vs 4.7) and iOS requirement (11.0 vs 15.0). Physics Lab AR's advantage is ratings volume (1.9K vs 4). On price, ads and device support there is nothing between them.

Both are free to download. Physics Lab AR sells 7 in-app purchases, starting at $1.49 per month. gravity detector asks for nothing beyond the download.

gravity detector holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Physics Lab AR has 1.9K ratings behind it against 4, so its average is the more settled of the two.
