# Frequency vs Magnetic Sensor

Frequency and Magnetic Sensor are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

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

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
