Your field logbook, on your phone - build any survey, powered by your device.
• Fits almost any field survey — define your own sections and variables with a simple template
• Let your device do the work — automatic timestamps, one-tap GPS, and photos attached right to each record
• Capture once, export clean — your data goes straight into an accurate, analysis-ready spreadsheet
• Private by default — your data stays on your device, no account or third-party cloud required
── How it works ──
1. Get a template — a .yaml file that defines your survey's structure
2. Import it — paste a URL, scan a QR code, or open a local file
3. Collect data in the field — quickly log each new observation
4. Export when done — get an XLSX or ODS spreadsheet for analysis

── Design your own survey ──
Field Survey runs on templates you define, so it fits almost any survey:
• Organized into sections — build your survey from sections that nest parent-to-child, each holding its own variables
• Variable types — Text, Int, Float, Boolean, Date / Time / DateTime, Option, OptionCount (count per option), Map (location, path, polygon), Photo, Markdown (with more types on the way)
• Deeply configurable — adjust both sections and variables to fit your exact workflow (full list in the guide)

── Permissions ──
Field Survey only asks for what a feature needs:
• Internet — to load map tiles and import templates from a link
• Location — to show your current position on the map
• Camera — to take photos for photo variables
• Photos & storage — to attach images and save your exported spreadsheets
── What's next ──
Planned ideas include more variable types, multiple languages, iOS support, and optional sync to your own server.
This is a solo project — your feedback and support help these arrive sooner.
