TopAssist is a field inspection app for surveyors, site supervisors and technicians. On site, the Android app turns each observation into a geolocated point with photos, annotations (circle, arrow, cross, distance bar), comments linked to the photos they describe, and a color category. Everything syncs in real time to the office web app, where the team reviews the map and exports the visit in one click: editable Word report, HTML report, GeoPackage with a ready-to-open QGIS project, or a ZIP of all photos. Coordinates in WGS 84 and Lambert-93, original GPS position and accuracy preserved, works offline. Company-wide presets for colors, report content and logo. French-language interface. 2-month free trial, no credit card.
