Phone Tools
Your phone's sensors as site gauges — a spirit level, an angle finder and a sound meter. Best on a phone. Nothing is recorded or uploaded; sensors only run after you tap to enable them.
0.0°left–right
0.0°front–back
Lay the phone on the surface. "Zero" sets the current tilt as flat — handy for checking relative level on an out-of-level bench.
0.0°
from horizontal
Hold the phone flat against the surface, long edge along it. Reads tilt from horizontal (0°) up to vertical/plumb (90°).
–– dB (relative)
Peak: –– dB
Relative, not calibrated SPL. Phone mics roll off and clip — use it to compare loudness, not for compliance or hearing-protection decisions.
