FieldKit

One app for surveyors, engineers, and GIS professionals who work where signal dies. Most tools run fully offline. Map tiles load when connected.

## WHY FIELDKIT

Stop juggling apps. FieldKit replaces your calculator, GPS tracker, map viewer and compass with one tool that respects your battery and your privacy. No account. No ads. No subscriptions. No data collection.

## QUICK TOOLS — FULLY OFFLINE

Length & Area — Metric, imperial, and Nepali land units (Ropani, Aana, Paisa, Dam). Add, subtract, convert, swap instantly. Keep history.

Loan & Price — EMI schedules with Nepali date support. Export PDF repayment reports. Price land by unit area with readable Nepali/international formatting.

Draw — Sketch polygons on canvas. Diagonal splits, triangulation, pan, zoom. Side lengths, perimeter, area.

Calendar — Full Bikram Sambat with AD↔BS conversion, date difference, festivals, tithi, and home widget.

Compass — Live heading, degrees, cardinal direction, level bubble, calibration hints.

QR Scan — Camera scan with auto-parse for URLs, WiFi, UPI, maps, contacts. History, torch, camera switch.

## SURVEY & MAP TOOLS

Image Measure — Digitize scanned maps and parcel plans. Polygon vertices, ruler mode, split parcels, undo. World file and TFW georeferencing. Export GeoJSON, SHP, CSV.

Satellite Measure — Tap polygons on live ESRI imagery. GPS centering, side labels, self-intersection guard. Requires internet. For estimates, not survey-grade.

Map Workspace — Import CSV, KML, GeoJSON, SHP (with DBF/PRJ), GeoTIFF. Layer management, linework, polygons, labels. UTM and geographic coordinates. Raster overlays with opacity control. Ground control point georeferencing with residual review. Fit to data. Export GeoJSON, SHP, CSV.

Bearing — Traverse angles, clockwise/counterclockwise, segment distances. Export PDF reports.

DEM & Contours — IDW interpolation from elevation points. Colour raster grids, smooth contour lines with major/minor intervals and labels. Quality scales with point density.

Tracker — Live GPS routes with speed, distance, duration, average and max speed. Points with remarks and timestamps. Geographic or UTM. GeoJSON export. Map with basemap switch, auto-follow, fullscreen.

Buffer — Real-time buffer zones around points, lines, polygons. Preview and export GeoJSON, SHP, CSV.

Earthwork — Cut and fill volumes from DEM against base level. Cubic-metre reports.

Sections — Longitudinal and cross-section profiles. Terrain, grade, utilities. Export PDF/PNG.

## SURVEY-GRADE GNSS — ANDROID ONLY

Connect external Bluetooth Classic receivers. Live position with latitude/longitude or UTM, altitude, fix type, satellites, DOP, speed, accuracy. Satellite sky plot with polar view. Forward NTRIP internet corrections for RTK precision. Supports GSOF and NMEA. Receiver must be paired in Android settings first.

## NO ACCOUNT. NO ADS. NO SUBSCRIPTIONS.
