Open GeoJSON on Phone

GeoJSON is a JSON format for geographic points, paths, polygons, and feature collections.

• Phone browsers and chat apps usually show GeoJSON as raw JSON.
• Large coordinate arrays are hard to understand on a small screen.
• You may only need to confirm whether the file contains points, lines, or polygons.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
