# Angle Gradient Inclinometer vs Magnetometer+

The clearest difference is review sentiment: Magnetometer+ at 100% against Angle Gradient Inclinometer's 51%. Magnetometer+ also leads on update cadence (every 4 days vs every 8 months). Angle Gradient Inclinometer's advantage is rating (4.4 vs 2.7) and ratings volume (295 vs 7). 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.

Angle Gradient Inclinometer holds the better App Store score, 4.4 against 2.7. That said, the two scores are not equally well evidenced: Angle Gradient Inclinometer has 295 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 51% of Angle Gradient Inclinometer's written reviews are positive against 100% of Magnetometer+'s, so the app with the better star average is not the one people write more warmly about.
