# Gravitational Wave Events vs gravity detector

The clearest difference is ratings volume: Gravitational Wave Events at 133 against gravity detector's 4. gravity detector's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

gravity detector holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Gravitational Wave Events has 133 ratings behind it against 4, so its average is the more settled of the two.
