📱 Google Play App StoreA general-purpose GPS map tool for marking points, measuring areas, recording tracks, and on-site reference. Not a legal-grade survey instrument — great for self-check, outdoor work, and everyday location tasks.
Waypoint, route, and track navigation with map / satellite view switching and compass direction. Return-to-start when you lose your way.
Walk-and-measure area calculation with mu and other units. Quick estimation for farmland, forest, and plots — for reference only.
Coordinate collection and marking for power lines, railways, and geological surveys. On-site reference for construction layout and self-check.
One-tap coordinate capture with custom naming. Navigate back to a saved point, or find any location by entering its coordinates.
Build routes from waypoints and navigate point by point. Record tracks and import / export GPX / KML to share with other map apps.
GEO camera photos auto-tagged with GPS coordinates. Batch export points, routes, and tracks in GPX / DXF / SHP / CSV formats.
Many survey apps force you to create an account and upload data to the cloud. SiteStake is different — no account system, no personal data collection, everything stored locally. Works fully offline.
Download and use immediately. No email, no phone number.
100% local storage in app sandbox. Data never leaves unless you export.
Clean experience. No ad SDKs, no tracking, no analytics.
