Phone compass-clinometer

Lay the back of the phone on the plane and press Record. Each record is the mean of the last 30 sensor samples, corrected to true north.

Import measurements

Plane notation

Paste rows (type, azimuth, angle, set)

P = plane (bedding, joint, fault, foliation); L = line (lineation, fold axis, slickenline) as trend, plunge.

Sets and display

Set assignment

Number of sets k

Pole density contours (Kamb) Great circles of all planes Set means with α95 cones

Slope face for kinematic analysis

Run the kinematic analysis

Face dip direction (°)

Face dip (°)

Friction φ (°)

Planar limit (°)

Toppling limit (°)

Measurements

Stereographic analysis of orientation data

Record planes with the phone, type them or paste a field sheet, then analyse: pole density, set statistics, fabric eigenvalues, rose diagram and kinematic analysis against a slope face.
