F vs Maps Ruler

Đo Đất turns your phone into a simple land-measuring tool. Tap the corners of a plot on a satellite map, or walk its boundary with GPS, and instantly see the area and perimeter - no surveying gear needed. HOW IT WORKS - Open the satellite map and drop points around your plot (tap to add corners, or use your GPS location). - Đo Đất measures the enclosed area and the perimeter as you go, and draws the boundary on the map. - Switch area units (square meters, hectares, and more) to match how you work. - Save each plot with a name and notes (crop, season) so you can find it again. SATELLITE IMAGERY, NO SETUP The map uses free satellite imagery, so you can see real fields and boundaries without any API key or configuration. OPTIONAL: SYNC TO F-LOSNING If you use the F-Losning farm platform, connect your account to sync saved plots to a farm - the measured area and boundary then appear in F-Losning. This is completely optional; measuring works fully offline without an account. Đo Đất (Measure Land) has a Vietnamese interface. It needs location permission to show your position on the map, but you can also measure by tapping points without granting location.
