GeoProof
Offline GPS camera for field work

Photos that show where and when, honestly.

GeoProof stamps every photo with its capture time, coordinates and accuracy, then organises your evidence into projects, inspection checklists and clean PDF reports. Everything works without internet, and nothing leaves your phone unless you share it.

GeoProof camera screen with a live GPS stamp showing the date, time and project name. Location details are blurred in this image.

Everything a site visit needs

Built for property inspectors, maintenance crews, builders and anyone who has to prove the work was done.

GPS camera with live stamp

See the stamp before you shoot. Time with time zone, coordinates in decimal, DMS or DDM, accuracy, altitude and compass direction.

Projects, visits and notes

Group photos by site or job, record visits, keep notes and an activity log. Save the site's location with one tap.

Inspection checklists

Property, maintenance, construction and general templates. A completeness check flags unchecked items, missing photos and open issues.

PDF reports

Summary, checklist table, before/after pairs and photos at 1, 2 or 4 per page. Telugu and other scripts render correctly.

Originals never altered

The stamp goes on a separate copy. Your original stays byte-for-byte as the camera saved it, with a SHA-256 fingerprint.

Built for no signal

Capture, stamps, projects and reports all work offline. Photos survive the app being closed mid-capture.

A look inside

Real screens from the Android app. Location details are blurred in these images.

Field photos, organised: home screen with projects, recent photos and reports.
GPS stamp on every photo: camera screen showing time, coordinates and optional address.
Your original is always kept: photo viewer, with the stamp on a separate copy.
Five stamp styles: editor to pick fields, position, colours and logo.
Inspection checklists: issues with severity and status.
PDF reports on your phone, shared with Android's share sheet.

Honest by design

A stamp is only useful if people can trust it. GeoProof never fills gaps with guesses.

  • No location fix? The photo says “Location unavailable”. Coordinates are never invented.
  • Old or inaccurate fix? It's labelled, for example “GPS fix 3 min before capture”.
  • Capture time and GPS fix time are recorded separately, with the time zone.
  • Imported photos are marked imported, and their metadata is marked unverified.
  • Reports list every caveat in a disclosures section.
