Magnes is a precise, instrument-grade magnetic field meter that reads your device's built-in magnetometer and displays live strength in microtesla (µT).
Clean and focused — one screen, one job. No ghost-hunting theatrics, no ads, no account required. Everything runs locally on your device.
Features:
• Live reading with an analog-style gauge and color-coded zones (Normal / Elevated / High)
• 30-second rolling chart with per-axis X/Y/Z breakdown
• Peak Hold — freeze and track the highest reading (Pro)
• Session Recording — log a timed measurement to review later (Pro)
• CSV Export — share raw timestamped data from any session (Pro)
• Unlimited session history stored on-device (Pro)
Magnes Pro is a one-time purchase — no subscription, no hidden fees.
