# phyphox vs gravity detector

The clearest difference is rating: gravity detector at 5.0 against phyphox's 4.6. phyphox's advantage is ratings volume (282 vs 4) and chart position (#201 vs unranked). 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 4.6. That said, the two scores are not equally well evidenced: phyphox has 282 ratings behind it against 4, so its average is the more settled of the two.
