Use your iPhone or iPad to capture practical environmental readings and organize them into simple survey records.

Key features:
- Light meter for estimated Lux readings
- Color temperature (CCT) estimation with calibration offset
- Noise level meter in dB
- Compass and altitude display
- Blueprint/photo mapping with tap-to-record survey points
