GeoProof turns your iPhone into a GPS field camera that proves exactly when, where, and in what conditions every photo was taken — built for inspectors, surveyors, construction crews, and anyone whose photos have to hold up later.
WHAT GETS STAMPED
- GPS coordinates (decimal, DMS, MGRS, UTM)
- Altitude, accuracy, heading, speed and bearing
- Reverse-geocoded street address
- Date, time and time zone
- Live weather at the moment of capture
- Project name, notes and your company logo
- A map inset pinning the exact spot
PROOF YOU CAN STAND BEHIND
Every photo is cryptographically signed on-device and tamper-evident, so you can show a file hasn't been altered since capture.
ORGANIZED FOR REAL WORK
- Group captures into projects per site or job
- Search and filter by address, date or coordinates
- Export branded PDF reports, photo bundles and GPX tracks
- Apple Watch app, Home Screen widget and Spotlight
PERFECT FOR
Construction progress, site & safety inspections, land and utility surveying, insurance claims, real estate, environmental and field research, legal documentation.
Note: GeoProof's signature makes tampering evident; it is not a legal chain-of-custody guarantee.
COMMON QUESTIONS
What exactly does it stamp on a photo?
Coordinates in the format you pick (decimal, DMS, MGRS or UTM), altitude, accuracy, address, date and time, compass bearing, and the weather at that moment. You choose which of those appear and where.
Is it proof in a legal sense?
It is evidence, not proof. It records what the phone's GPS, compass and clock reported at capture time, and shows the accuracy figure so you can judge it. No app can certify that a phone was not fooled.
Does it need internet?
Not for capturing. The address and the weather need a connection; coordinates, altitude and bearing do not. Offline maps can be downloaded ahead of the job.
What can I hand over at the end?
A PDF report, a spreadsheet, a KML or GeoJSON, or the whole project as a bundle.
Is there a watermark on free photos?
Your overlay is the watermark and you design it, including your own logo on Pro.
Does it work on iPad?
Yes.
