Draw, measure and export field-grade geometry from your phone. Works offline. 35+ coordinate systems. 46 languages. Free.
Eight capabilities that cover the full life of a site survey.
Points, lines and polygons with 5 m auto-snap. Tap-to-drop vertices, undo, redo and precise manual entry.
Unlimited layers per project, per-layer color, visibility and style. Switch between projects in one tap.
One-tap capture of your live GPS location as a point — with elevation, accuracy and timestamp baked in.
Record your walking or driving route in real time. Pause, resume, edit and export the polyline with full timestamps.
Area, perimeter, distance, bearing and 3-point angle. Metric or imperial, live readout while you draw.
Slope along any segment in percent, permille or degrees. Two-point and along-line modes for grading work.
Elevation profile and cross-section graphs along any line, sourced from SRTM DEM. Min, max, ascent and descent in one chart.
Generate equal-elevation contour lines automatically from SRTM DEM data. Choose the interval and overlay on any basemap.
