Measure light. Sleep better.
Having trouble with LumaKit? We're here to help. Most issues can be resolved by making sure you've granted camera access in Settings → LumaKit → Camera.
The reading seems inaccurate.
Smartphone-based lux measurement is approximate. If you have access to a
reference lux meter, you can adjust the calibration multiplier in
Settings to improve accuracy.
The app shows "Measuring..." for a long time.
LumaKit waits for the camera's auto-exposure to stabilize before
showing a reading. This usually takes a few seconds. If it persists,
try restarting the app.
Does LumaKit store photos or video?
No. LumaKit only reads exposure metadata from the camera feed.
No images or video are recorded or stored.
