Pinproof: Site Photo Report

Pinproof turns job site photos into a PDF site photo report. Every photo is stamped with date, time, GPS location and address, and kept by job. Take before and after shots from the same spot and send a report with a site map. Made for contractors, inspectors and field teams.

Proof That Holds Up
• Date and time stamp, GPS coordinates, accuracy and street address on every photo
• The stamp says when the GPS is real and the time was checked by satellites
• It warns if a fake-GPS app was on, so a faked location is easy to spot
• Ask before shooting when GPS is poor, with the real accuracy always shown
• Your original photo is kept unchanged and geotagged, with GPS in its EXIF data

Before and After From the Same Spot
Open an old photo and tap Take the "after". The old photo shows faded over the camera, an arrow and distance lead you back to where it was taken, and Pinproof tells you which way to turn. The new photo is paired as the "after" automatically.

Add Location and Time to Photos You Already Took
Add a photo from your gallery and it is stamped with the time and place saved in it. With Pro, stamp a whole batch at once. The stamp says the details came from the file, so it is never mistaken for a live photo.

Job Site Photos and Reports
• Keep photos by job, with a site name and job number on every stamp
• Add a note to any photo, and edit the address or note later
• Export a PDF site photo report with every photo, its details, a before/after section and a site map of where each photo was taken
• Export a spreadsheet (CSV) and a Google Earth file (KML)

Your Stamp, Your Way
Choose what goes on the stamp, move it to any corner, change its size, date format and 24-hour time. Pro adds your company logo and more templates.

Private and Works Offline
No account, no sign-up. Your photos stay on your phone and are never uploaded. The camera and GPS work without internet; the street address fills in when you are back online.

Free and Pro
Pinproof is free to use for stamped photos, projects and reports of up to 10 photos. The free version shows a small banner on the project screen, never on the camera, and a small Pinproof credit on the stamp.
Pinproof Pro adds:
• Your company logo on the stamp
• All stamp templates
• Stamp many old photos at once
• Reports of any size, plus CSV and KML export
• No credit and no ads
Pro is a one-time purchase or a yearly plan. No weekly plans.

Pinproof is a record-keeping tool, not a certified timestamping service. GPS can be less accurate indoors.
