Proof burned into every photo.
GeoProof is a GPS camera for people who need their photos to say where and when. Coordinates, street address and time are printed straight into the image — not buried in metadata your client will never open.
What gets stamped
- Latitude and longitude, with the accuracy the handset reported
- Street address
- Date and time, checked against a public time server
- Compass heading and altitude
- Weather at the moment of capture (optional, off by default)
- Your own logo and job name
Position comes from satellites, so the coordinates, altitude and heading all work with no signal. Turning coordinates into a street address needs a connection — GeoProof fills that field in as soon as one is available, and leaves it blank rather than guessing if it isn't.
One-tap PDF reports
Turn a day of site photos into a clean PDF. Group by job, add notes, pair before and after shots, sign it, send it. Each page carries the stamped photo itself alongside a summary line of the coordinates, accuracy and timestamp that went into it, so the record travels with the invoice rather than getting assembled from memory back at the office.
Your photos stay on your phone
No account, no cloud, no sign-up. Your photos, notes and job records never leave your device — there is no server for them to go to. GeoProof does make a few small network requests, and they are all listed plainly in the privacy policy.
Integrity check
Every photo gets a SHA-256 fingerprint the moment it is taken. Re-check the file later — after it has been emailed, uploaded, or copied off the phone — and GeoProof tells you whether that exact file has changed since. That is the whole claim: a change check, and nothing beyond it.
GeoProof does not certify anything and is not a legal service. It reports what it can actually measure, and nothing beyond that.
One price, paid once
No subscription. No ads. No credits. Unlock Pro once and keep it — handled entirely by Apple or Google, so GeoProof never sees a card number. There is no venture-backed company behind the app subsidizing a free tier by tracking you; the one-time purchase is the entire business model.
