# Sensors Toolbox vs Magna

The clearest difference is review sentiment: Magna at 100% against Sensors Toolbox's 53%. Magna also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). Sensors Toolbox's advantage is rating (4.2 vs 3.5) and ratings volume (134 vs 8). On price, in-app purchases and device support there is nothing between them.

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

Sensors Toolbox holds the better App Store score, 4.2 against 3.5. That said, the two scores are not equally well evidenced: Sensors Toolbox has 134 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 53% of Sensors Toolbox's written reviews are positive against 100% of Magna's, so the app with the better star average is not the one people write more warmly about.

Sensors Toolbox ships an update every 7 months, Magna every 3 weeks. The most recent releases landed on October 24, 2026 and October 9, 2026 respectively.
