Field Camera.

A minimal camera that records where you stood and which way you faced — burned into every photo, plotted on a map.

Field Camera is a minimal position-and-bearing camera app for iPhone. Every photo you take has its GPS coordinates and compass heading burned directly into the image, and is named in a running sequence — field-001.jpg, field-002.jpg — so a filename always matches its numbered pin on the map. It plots each capture on an offline map with a numbered pin and a direction cone showing which way the camera was pointed. You can print the map, a data table of coordinates and bearings, and a contact sheet of the photos, and back the whole workspace up as a single JSON file or export a CSV. It is a Progressive Web App: it installs to your iPhone home screen from Safari, works offline, and needs no account. Built by Backfield, a small software studio, for site documentation, surveying, real-estate, trail mapping, and anyone who needs to remember exactly where they stood and which way they were facing.

A camera that remembers where.

Field Camera is for people who take photos in the field and need to know, later, exactly where each one was taken and which way it was pointed. Every shot records its GPS position and compass bearing and burns them right into the image. That's the whole idea.

Each photo is numbered in a running sequence — field-001, field-002 — and that same number is the pin on the map. The number never resets, so a filename always points to one place on one map. Built by someone who documents sites for a living.

The whole feature list.

  1. 01

    Capture

    Point, shoot. The photo saves with GPS coordinates, compass bearing, and a timestamp burned into a strip along the bottom. Nothing to fill in.

  2. 02

    Sequence

    Every capture gets the next number in line. The number is permanent — deleting a shot leaves a gap rather than renumbering — so field-014 always means the same photo and the same pin.

  3. 03

    Map

    Every located capture plots on an offline map as a numbered pin with a cone showing which way the camera faced. Tap a pin to review or delete it.

  4. 04

    Print

    Print the map, a data table of every coordinate and bearing, and a contact sheet of the photos — any combination. Preview the sheet on screen first.

  5. 05

    Back up

    Export the whole workspace as one JSON file to restore later, or a CSV to open in Excel, Numbers, or Sheets. Your call, your file.

Add to home screen.

Field Camera is a Progressive Web App — it runs in your iPhone's browser, but you can install it to your home screen so it opens like a native app. Nothing to download from the App Store, and it works offline once installed.

  1. Open backfield.io/field-camera in Safari on your iPhone
  2. Tap the Share button at the bottom of the screen
  3. Scroll down and tap Add to Home Screen
  4. Tap Add in the top right

It appears as a regular app icon, opens full-screen, and asks for camera, location, and compass access the first time — all three are needed to record a photo with its position and bearing.

What it isn't.

Some things this app does not do, on purpose — and a couple of real limits worth knowing:

  • No accounts, no logins, no cloud sync — your captures live on your device
  • No editing, filters, or albums — it's a recording tool, not a photo app
  • The map uses volunteer OpenStreetMap tiles — fine for personal fieldwork, not heavy commercial traffic
  • Photos save to your camera roll on capture; the JSON backup holds the map data, not the full-resolution images
  • Compass bearing is only as good as your phone's magnetometer — calibrate it if a reading looks off
  • Built and tested for iPhone — it may run elsewhere, but that's not what it's for

Free to use. Made by Dan at Backfield, a small studio.
