# Physics Toolbox Magnetometer vs Vernier Spectral Analysis

The clearest difference is review sentiment: Physics Toolbox Magnetometer at 80% against Vernier Spectral Analysis's 21%. Physics Toolbox Magnetometer also leads on rating (5.0 vs 2.2). Vernier Spectral Analysis's advantage is in-app purchases (none vs 1) and ratings volume (61 vs 7). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Physics Toolbox Magnetometer sells 1 one-off in-app purchase. Vernier Spectral Analysis asks for nothing beyond the download.

Physics Toolbox Magnetometer holds the better App Store score, 5.0 against 2.2. That said, the two scores are not equally well evidenced: Vernier Spectral Analysis has 61 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 80% of Physics Toolbox Magnetometer's written reviews are positive against 21% of Vernier Spectral Analysis's.

Physics Toolbox Magnetometer ships an update every 13 months, Vernier Spectral Analysis every 8 months. The most recent releases landed on October 9, 2026 and October 16, 2026 respectively.
