Lux Meter: Light Level

☀️ Lux Meter — ambient light level in lux on your phone

Need to check if a desk is bright enough, compare a room to typical office light, or hold a peak reading while you move the phone? Lux Meter uses the Android ambient light sensor for a live lux (and foot-candle) readout with scene guides.

No accounts and no cloud — on-device light metering when you need a quick check.

🔊 How it works

1️⃣ Tap Start to read illuminance from the light sensor

2️⃣ Watch the live dial and peak value as lighting changes

3️⃣ Compare the active scene guide (dim / home / office / daylight / outdoor)

4️⃣ Switch lx ↔ fc; Reset peak when you start a new pass

⚠️ Approximate phone sensor reading. Not a calibrated lab lux meter. Sensor available on Android devices that expose it.
