# Gaussmeter NS pole vs Magnetometer / Gaussmeter

The clearest difference is price: Gaussmeter NS pole at Free against Magnetometer / Gaussmeter's $0.99. Gaussmeter NS pole also leads on review sentiment (71% vs 50%) and update cadence (every 17 months vs every 40 months). Magnetometer / Gaussmeter's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 1). On device support there is nothing between them.

Gaussmeter NS pole is free to download; Magnetometer / Gaussmeter costs $0.99 up front. Gaussmeter NS pole sells 1 one-off in-app purchase. Magnetometer / Gaussmeter asks for nothing beyond the download.

Magnetometer / Gaussmeter holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Gaussmeter NS pole has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 71% of Gaussmeter NS pole's written reviews are positive against 50% of Magnetometer / Gaussmeter's, so the app with the better star average is not the one people write more warmly about.

Gaussmeter NS pole ships an update every 17 months, Magnetometer / Gaussmeter every 40 months. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
