Full description

Lumen turns your Android device's ambient-light sensor into a clear, focused light meter. Read the light reported by your device sensor in lux, from pitch dark through indoor workspaces to bright daylight. A responsive log-scale gauge makes large changes easy to understand, while the rolling history shows how lighting changes over time. Features: • Live ambient-light measurement in lux • Color-responsive log-scale gauge • Human-friendly light-level descriptions • Rolling 90-second history chart • Hold and resume a reading • Share a reading using Android's share sheet • Save a local snapshot to Pictures/Lumen Lumen works entirely on your device. It has no account, ads, analytics, or network service. Sensor readings and the temporary history stay local. Sharing and snapshots happen only when you choose them. Note: readings depend on your device's ambient-light sensor and local conditions; use them as an informational measurement, not as a certified calibration instrument.

What's new

• Fix: the rolling history chart now records on a steady interval, so the graph keeps recording and scrolling even when light is constant (previously it only advanced when the sensor value changed).
