About this app

FieldGauge is an offline-first engineer toolkit for phones. Measure, log and convert on device — without sending sensor data to the cloud.

Included tools
• Illuminance & exposure — lux, EV100, shutter/aperture/ISO helpers
• Level, slope & compass — pitch, roll, magnetic heading
• Vibration analyzer — RMS, peak, dominant frequency, baseline change
• Sound & frequency — relative level, optional SPL estimate after calibration
• Environment — pressure, relative altitude, temperature, humidity (when fitted)
• AI instrument reader — on-device OCR for meters and nameplates
• Screen ruler and engineering unit converter

Designed for field work
• Works without INTERNET for measurement tools; optional ads use network when shown
• Sensors checked at runtime — missing hardware is shown as not fitted
• Local CSV measurement log with user-controlled export
• One-time Remove Ads purchase available (org.igears.lightmeter.remove_ads)

Accuracy notice
Phone sensors vary by model and are not certified instruments. Calibrate against a traceable reference before professional, regulatory or safety-critical use. Results are for reference only.
