🗺️ Yard
Map the lawn once — every plan starts here. Estimates only: always walk your yard and check slopes and obstacles yourself before mowing.
Map
Import a trace or walk the boundary —
your yard will draw here.
Drag to pan · pinch or scroll to zoom · double-tap to zoom in. No satellite tiles — Mow Planner is fully offline; trace over imagery at geojson.io and import below.
Your yards
⬆️ Import your yard — GeoJSON · GPX · KML
Three ways in, all offline:
1. Trace it over satellite — open geojson.io or Google Earth, draw a polygon around the lawn (draw the beds and playset too, and drop a point on each tree), save as GeoJSON or KML, import here.
2. Walk it — record a track all the way around the lawn edge in any GPS app (Gaia, onX, AllTrails…), export the GPX, and the boundary draws itself.
3. Bring your marks — waypoints from a Garmin, onX or Gaia export become obstacles inside the yard.
📍 Walk or draw the boundary
Stand at each corner of the lawn and mark it with GPS — or tap corners straight onto the map above.

Changes save instantly and recompute every estimate. Measure your true cutting width blade-tip to blade-tip — it's often less than the deck badge says.
