Light meter & lux meter for Wear OS. Measure ambient illuminance on your watch.
Turn your smartwatch into a reliable, accurate lux meter and ambient light meter. This standalone Wear OS application allows you to monitor and measure ambient illuminance directly from your wrist, leveraging your smartwatch's built-in light sensor in real time. Ideal for photography exposure checks, indoor plant care, workplace lighting compliance, cinematographers, architectural design, and technical field inspections. Key Features: Real-Time Light Measurement: Instant, continuous illuminance readings in lux (lx) directly on your wrist with this standalone luxmeter. Dual Units: Easily switch between lux and foot-candles (fc) for your lighting measurements. Dynamic Live Graph: Track illumination trends and light intensity changes over time with a smooth visual chart tailored for round and square smartwatch screens. Capture & Save Sessions: Instantly capture the current graph data with a single tap, logging minimum, maximum, and average values (Min / Max / Avg). Location Logging & Data Export: Record measurements along with GPS coordinates and easily export your data logs (CSV / text format) to share, document, or analyze inspection reports. Custom Calibration: Fine-tune readings and adjust sensor multipliers to align with dedicated reference lux meters or photometer standards. 100% Standalone for Wear OS: Operates completely independently on your smartwatch without requiring a companion phone app or constant tethering. Battery-Efficient Interface: Designed with deep black OLED/AMOLED backgrounds to maximize watch battery life while maintaining clear readability in bright sunlight and dark environments. Common Use Cases: Photography & Video: Incident ambient light checks on set or on location. Horticulture & Plant Care: Ensure optimal light intensity for indoor plants, greenhouses, and grow lights. Workplace Compliance: Verify ergonomic lighting standards across offices, workshops, and commercial spaces. Auditing & Reporting: Log lighting levels with timestamped coordinates and export historical data for compliance records. Note: Measurement accuracy and maximum lux range depend directly on the ambient light sensor hardware integrated into your specific Wear OS smartwatch.
