# Magnetometer / Gaussmeter vs Pole Detector

The clearest difference is price: Pole Detector at Free against Magnetometer / Gaussmeter's $0.99. Pole Detector also leads on update cadence (every 10 days vs every 40 months) and review sentiment (60% vs 50%). Magnetometer / Gaussmeter's advantage is rating (5.0 vs 4.8) and iOS requirement (8.0 vs 11.0). On ads, in-app purchases and device support there is nothing between them.

Pole Detector is free to download; Magnetometer / Gaussmeter costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Magnetometer / Gaussmeter holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Pole Detector has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Magnetometer / Gaussmeter's written reviews are positive against 60% of Pole Detector's, so the app with the better star average is not the one people write more warmly about.

Magnetometer / Gaussmeter ships an update every 40 months, Pole Detector every 10 days. The most recent releases landed on October 2, 2026 and October 12, 2026 respectively.
