WristLux: Wear OS Light Meter

Wear OS light meter: live lux, modes, Tile & complication.

WristLux is a simple ambient light meter built for Wear OS.

Use your watch to check live lux readings, compare light with practical modes, hold a reading, and track session min, max, average, and duration. WristLux also includes a Wear OS Tile and watch face complication so your latest saved light reading is easy to glance at from your watch.

Use WristLux for quick light checks around everyday situations:

- Desk and reading light
- Plant placement and grow-light checks
- Photo and video scouting
- Indoor, outdoor, and evening light awareness
- General ambient light reference from your wrist

Key features:

- Live lux reading from the watch ambient light sensor
- Lux and foot-candle units
- General, desk, reading, plant, photo, outdoor, and evening modes
- Hold current reading while the live meter keeps running
- Session min, max, average, and duration
- Basic calibration adjustment
- Wear OS Tile with latest saved reading and freshness status
- Watch face complication with latest saved reading
- Standalone Wear OS app with no account or phone companion required

The Tile and complication use the latest reading saved by the main app. They do not continuously poll the light sensor in the background.

Ambient light readings are approximate and vary by watch model, wrist angle, shadows, cases, sleeves, and sensor placement. WristLux is a quick light reference, not a certified professional light meter.
