Hva er Dark Sky Meter Pro-appen? Dark Sky Meter Pro turns your iPhone’s camera into a sky brightness meter. Point at the night sky to get scientific readings in SQM (magnitudes per square arcsecond) and Bortle scale, plus NELM (naked-eye limiting magnitude) and an estimate of visible stars—so you can track light pollution and compare sites.

Measure

One-tap measurement: cover the lens for a dark frame, then point at the sky. Results in seconds.

Device-specific calibration (zero point) for better accuracy; optional FOV setting (default 20° for SQM-style comparison).
Readings include location and time for your records.

My Data
Save measurements locally and, with Sign in with Apple, sync across your devices.
Export to CSV for analysis or sharing.
Review history with SQM, Bortle, NELM, and location.

Map
