# gravity detector vs Unreal Chemist

The clearest difference is rating: gravity detector at 5.0 against Unreal Chemist's 4.5. gravity detector also leads on in-app purchases (none vs 1) and ads (none vs shown). Unreal Chemist's advantage is ratings volume (68 vs 4). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase. gravity detector asks for nothing beyond the download.

gravity detector holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Unreal Chemist has 68 ratings behind it against 4, so its average is the more settled of the two.
