Free · tamper-proof · works offline
ProofCam stamps each photo with network-verified time, the GPS address and a unique Photo Code anyone can check online. Turn a day of site photos into a PDF or Excel report in seconds.
Drop a photo or video to check it on this device — whether it is the original and what evidence it carries. Or type a Photo Code to look it up online.
Checking…
Files are verified in your browser and never uploaded — the check works offline. Verification never reveals who took the photo.
Features
ProofCam replaces the camera app, the timesheet and the report template. Shoot on site, and the evidence is already organised when you get back.
Time comes from network and satellite clocks, not the phone setting — changing the date on the device changes nothing. Address, GPS and weather are stamped at the moment of capture.
Every photo carries a unique 14-character code. Clients check it on this page and see the original time and place — and whether the file was changed.
Ten ready-made templates or your own: company logo, mini map, weather, compass, notes, tags, counters and custom fields.
Clock in, take a break and clock out with a stamped photo. Working hours add up automatically and export to Excel.
Inspection and cleaning checklists with items that require a photo. Fill them on site and send a PDF.
Select photos and export a PDF report, an Excel sheet, a ZIP of originals or a KMZ for Google Earth. Make before/after collages.
Photos sync automatically to your team. Organise work by project, set roles and permissions, send clients a live share link and push events to your systems with webhooks.

FAQ
ProofCam never trusts the phone’s clock. It syncs with network time servers (NTP) and the GPS satellites, then anchors that time to the phone’s uptime counter, which keeps running even when you change the date or time zone in settings. Without a network the last sync is still valid, so offline photos keep the correct time. Photos taken before the first sync are marked as unverified.
Each photo gets a unique 14-character code printed on the image and written into its EXIF data. When the photo is saved, ProofCam registers the code with the capture time, place and a SHA-256 fingerprint of the file. Enter the code above to see the original record. Add the file and we compare fingerprints: an exact match means it is the original. Chat apps like Zalo or Messenger recompress images, so a forwarded copy shows as a “modified copy” — but the code record still shows the original time and place.
Yes. Capture, watermarking, timesheets, checklists and exports all work offline. Addresses and weather fill in from the last known data, Photo Codes come from a pool stored on the phone, and Teamspace uploads wait in a queue until you are back online. Codes registered more than 24 hours after capture are flagged as late registration.
On your phone. Personal photos are never uploaded; only the Photo Code record (time, place and file fingerprint) is stored so the code can be verified. If you join a Teamspace, photos you take for that team are synced to the team’s cloud storage in Google Cloud’s Singapore region. See the privacy policy.
Free covers everything you need to take proof photos, with ads and exports of up to 10 photos at a time. Plus is a personal upgrade bought in the App Store or Google Play: no ads, company logo and map, editing the watermark after capture, originals and unlimited exports. Business is for teams: a shared Teamspace with 300,000 photos, unlimited projects, roles, the web portal, share links and webhooks, billed per member.
Yes. ProofCam is available for iPhone on the App Store and for Android on Google Play. Anyone can verify a ProofCam photo on this page from any phone or computer, and team managers can use the web portal from any browser.
With Plus you can change notes, tags or the template — never the time or location. The new file’s fingerprint is added to the code record, so verification shows “Edited by owner” instead of “Modified copy”, and the original capture data stays on record.
Time, place and a verifiable code on every shot — and the report is ready before you leave the site.
