Convert coordinates between 600+ systems — UTM, US State Plane, national grids and latitude/longitude — right on your iPhone, with no internet. Then take them to the field with GNSS survey, stakeout, maps and Live Layers for your team.
GeoShift is a geodesy toolkit for land surveyors, civil engineers, GIS users and field crews. It picks your country's national system automatically, and "Convert My Location" shows your position in any system with one tap.
► COORDINATE CONVERTER
• 600+ EPSG systems: WGS84, all UTM zones, US State Plane (NAD83, in each state's official unit: US survey feet, international feet or meters), NAD83 UTM, NAD27, NAD83(CSRS) and MTM, ETRS89, ED50, British National Grid, Lambert-93, GDA2020 MGA, JGD2011, SIRGAS, CGCS2000, Pulkovo 1942 and many more
• Official NTv2 grids for Germany, France, the Netherlands, Great Britain, Spain, Canada, Australia and New Zealand
• See the EPSG transformation code and its accuracy for every conversion
• Search by name, EPSG code or country; pick a point on the map
• DMS ↔ decimal degrees, QR sharing and PDF reports
► GNSS SURVEY (PRO)
• Multi-epoch averaging with outlier rejection (MAD) and Kalman filtering
• Quality metrics: horizontal standard deviation, 2DRMS (~95%), CEP50 and convergence
• Site calibration to local coordinates (Helmert, residuals and RMS)
► STAKEOUT + AR (PRO)
• Navigate to target points with compass, map, distance and bearing
• Augmented reality: target arrow and distance on the camera view
• True north with the WMM2025 magnetic model
► LIVE LAYERS
• Work on the same map with your crew: pins, lines and areas sync within seconds
• Invite by link or code as editor or viewer; changes made offline are sent when you reconnect
• Creating a layer and inviting require PRO; joining is free (sign-in required)
► MAP, DRAWING & EARTHWORK
• Measure distance and area; draw points, lines and polygons; move, rotate and undo
• Elevation profile and cut/fill volumes (PRO)
• Standard, satellite and terrain maps; HD satellite imagery (PRO)
• Download map regions for offline use
► FILES
• Open KML/KMZ with their folders, styles and labels, plus GPX, GeoJSON, Shapefile (.zip), DXF, CSV, Excel (.xlsx), LandXML and GML — even files with thousands of points
• Export to PDF, DXF, KML/KMZ, GPX, GeoJSON, Shapefile, CSV, LandXML and NCN
• Batch conversion of CSV/TXT/NCN files (PRO)
► MORE TOOLS
• COGO: inverse, forward, intersection and area
• Grid ↔ Ground scale factor
• GeoCamera: photos and videos with a GPS + UTM watermark
• Track recording with distance and speed (PRO)
• Cloud sync across your devices
• App languages: English, Turkish, Spanish, French, Hindi and Simplified Chinese
Features marked (PRO) require GeoShift PRO; everything else is free.
Position accuracy depends on your device's GPS and on site conditions.
