Capture field data where it happens. FieldSignal is the field data collection app built for renewable energy and environmental work: GPS-tagged notes, photos, checklists, offline maps, and AI-generated PDF reports in one app designed for sites with no signal.
Built by a founder with twenty years on wind, solar, and battery storage projects across the Americas and Europe.
CAPTURE ONCE, AT THE POINT OF OBSERVATION
• Text, voice-to-text, and photos with coordinates embedded at the moment of capture
• Annotate photos in the field with six drawing tools
• Scan barcodes and QR codes to identify equipment and link items to visits
• Video capture and voice notes
• Weather data captured with the visit
CHECKLISTS AND INSPECTION FORMS
• Build custom forms with nine field types, conditional logic, signatures, and in-form photos
• Start from the industry template library: solar PV, wind turbine, battery storage, and environmental templates
• Corrective actions and issue tracking
OFFLINE FIRST
• Capture, checklists and saved maps work with zero connectivity
• Capture all day; the app syncs automatically when a connection returns

PROFESSIONAL GIS
• Import shapefiles and georeferenced GeoPDF maps
• Draw and measure directly on the map
• Export as SHP, KML, and GeoJSON back into your GIS workflow
AI-GENERATED REPORTS

• Branded PDFs emailed from the app before you leave the site
• Your logo on your reports
TEAMS (Team plans)
• Shared visits with full attribution and audit trails
• Visit assignment, team map overlays, and consent-based location sharing

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New in this version:
• Add photos from your phone's library to a visit or a checklist. They are marked "Imported" in the app and in reports.
• Site access card: gate codes, site contacts, road hazards, parking and required PPE for each project, available offline.
• Plan visits for a day. Dated visits come first in your list.
• More dependable sync: it reconnects by itself, and one slow upload no longer holds up the rest.
• Clearer approval status on team projects, checklist photos in every report, and easier reading outdoors.
