iPhone
Stamp every photo with time, GPS and address, fingerprint it with SHA-256, and anchor it on-chain for independent verification.
OPCam turns your iPhone into a tamper-evidence camera for fieldwork, inspections, and any photo that has to be trusted.
• Time, GPS coordinates and address are burned into the original photo — they can't be edited out
• Every photo gets a SHA-256 fingerprint of the exact image file you share — so anyone holding the photo can recompute it and check it themselves
• Optional on-chain anchor: the fingerprint is recorded on Optimism, so anyone can independently verify the photo existed at that time
• Record library with timeline, place and live map views
• Choose exactly which fields go into the watermark
• 24 languages
Your photos stay yours — saved to your photo library. The on-chain anchor stores only a hash fingerprint, never the image.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Share a proof. Send the photo together with a JSON file holding its fingerprint and every watermark field, so whoever receives it can check it themselves.
• Back up and restore your whole record log — every record and every photograph in one archive.
• Manage storage: delete individual records, see how much space the log uses, and reclaim photos nothing references any more.
• A short guide on first launch, including a plain statement of what OPCam can and cannot prove.
• On-chain credits are now held on the server, so they survive reinstalling the app. Purchases that fail or need approval now say so instead of doing nothing.
• The watermark no longer runs off the edge of the photo on long addresses, and is laid out correctly in Arabic, Hebrew and Persian.
• Fixed a bug that could stop OPCam from reading back its own record log.
