Stamp, verify, and now go private. Photon Pro adds end-to-end encryption and more storage. Timestamping stays free forever. No jargon, just proof.
Prove your work is yours, from this moment on.
Photon gives any file a permanent, independently verifiable timestamp. Take a photo or pick a file, tap Stamp, and Photon creates proof that this exact file existed right now. Proof anyone can check, forever.
No jargon. Your files stay private.
• Stamp: photograph something on the spot, or pick a photo or document. Photon fingerprints the file on your device and timestamps it.
• Verify: check any file for a proof, no account needed. Hashing happens on your phone; the file never leaves it.
• Share proof: hand anyone a link or QR code so they can verify independently.
• Keep your shot: every capture is stored safely in your Photon files, with a quick preview right in the app, ready to download or share whenever you need it.
• Own your evidence: download portable .ots receipts that verify independently of Photon.
Photon Pro: your files, private.
Upgrade any time to add end-to-end encryption, right on your iPhone. Unlock with Face ID; only you hold the key, so Photon cannot read your encrypted files. Pro also raises your limits to 100 MB per file, 20 GB of storage, and 5,000 stamped files.
Photon Pro is an auto-renewable subscription: A$29.99 per year or A$2.99 per month (shown in your local currency at purchase). Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel any time in your iPhone Settings. See our Terms of Use (https://photon-rs.com/terms) and Privacy Policy (https://photon-rs.com/privacy) for details.
Made for photographers protecting their shots, creators and inventors establishing precedence, students and professionals proving submission dates, and anyone documenting what they saw, when they saw it.
How it works: Photon computes your file's SHA-256 fingerprint and anchors it via the OpenTimestamps standard to a public blockchain, creating an unforgeable, independently checkable record. Your file itself is never made public.
Stamping and verifying are free, forever. Your files, your proofs, yours to export or delete at any time.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Photon Pro is here.
Turn on end-to-end encryption right on your iPhone. Enrol once, unlock with Face ID, and Photon can no longer read your encrypted files, not even us. Forgot your passphrase? Your encryption recovery code gets you back in.
Pro also raises your limits: 100 MB per file, 20 GB of storage, 5,000 stamped files.
New: preview your files right in the app, including your encrypted ones once unlocked, with a privacy toggle so nothing shows unless you choose it.
Stamping and verifying stay free forever.
Plus fixes and polish throughout.
