# Gradiently vs phyphox

The clearest difference is review sentiment: phyphox at 79% against Gradiently's 50%. phyphox also leads on ratings volume (272 vs 3) and iOS requirement (12.0 vs 18.5). Gradiently's advantage is rating (5.0 vs 4.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Gradiently holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: phyphox has 272 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Gradiently's written reviews are positive against 79% of phyphox's, so the app with the better star average is not the one people write more warmly about.
