GeoProof: GPS Field Camera

GeoProof is a free GPS photo camera and offline field documentation tool. Take photos that show when and where they were taken, organise them into projects and inspection checklists, and turn them into clean PDF reports. No account, no subscription, no ads.

TIME AND LOCATION ON EVERY PHOTO
• Date, time and time zone from the device clock
• Latitude and longitude with the GPS accuracy (±m)
• Street address when your phone's geocoding service can find one (optional, off by default)
• Project name, notes and your own text on the stamp
• Missing, stale or approximate locations are clearly labelled, never guessed

FIVE STAMP STYLES
Classic GPS stamp, Minimal clean, Dark professional panel, Field inspection and Grid locator. Choose what to show, where the stamp goes, text size, colours, transparency, your company name and logo. Save presets and re-stamp existing photos. The preview and the saved photo use the same layout.

YOUR ORIGINAL IS KEPT
GeoProof keeps the untouched original and makes a separate stamped copy, so you can always go back to the original photo.

PROJECTS AND INSPECTIONS
• Projects with client, site, notes and visits
• Built-in inspection templates for property, maintenance, construction and general site visits, plus your own custom templates
• Mark items Satisfactory, Issue found or Not applicable, with severity and status
• Before-and-after photo pairs
• A completeness check lists unchecked items and missing evidence

PDF REPORTS
Project details, checklist and issue summary, numbered photos with captions, time and location, 1, 2 or 4 photos per page, your logo and accent colour. Reports are created on your phone and shared through Android's share sheet.

WORKS OFFLINE
Capture, stamping, gallery, projects and PDF reports work without internet. Address lookup needs a connection; when you are offline the photo is saved straight away and the address is added later.

PRIVATE BY DESIGN
• Photos and projects stay in the app's private storage on your phone
• No account, no cloud upload, no analytics, no ads
• Location is used only while the app is open, never in the background
• Nothing leaves your phone unless you share it

GOOD TO KNOW
GPS accuracy depends on your phone and surroundings and can be off by many metres, especially indoors. Addresses come from your phone's geocoding service and are approximate. A stamp is a visible annotation; it is not legal or cryptographic proof that a photo is authentic.
