# RED FPS vs HDR Diagnostics

The clearest difference is ratings volume: HDR Diagnostics at 5 against RED FPS's 1. RED FPS's advantage is iOS requirement (9.0 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 5.0 for RED FPS against 5.0 for HDR Diagnostics. That said, the two scores are not equally well evidenced: HDR Diagnostics has 5 ratings behind it against 1, so its average is the more settled of the two.
