Lens Proof-of-Work Camera
GPS & Content Credentials
Only for iPhone
Free · In‑App Purchases
Lens Proof is on the C2PA list of conforming products. With Lens Trust, your iPhone signs each photo and video as you take it, so anyone can check the original file.
Lens Proof is a field camera for iPhone that keeps the time, place, and weather on every photo and video. With Lens Trust, anyone with the original file can check when it was taken and whether it has changed.
• Shoot: Lens Proof geotags each capture and puts the date, time, and weather on the frame, with your note and logo. It works offline.
• Sign: With Lens Trust, your iPhone signs each capture the moment you take it, and a trusted timestamp is added.
• Check: Anyone can check a signed original file at check.lensproof.app, without an account.
• Report: Turn the day's captures into a PDF report in seconds. Pro and Trust add AI captions and a summary.
C2PA CONFORMANCE
C2PA is the open standard behind Content Credentials. Lens Proof is listed as a conforming product at Max Assurance Level 1, and Lens Proof Check, the checker at check.lensproof.app, is listed as a conforming validator. Anyone can look up both on the public C2PA list.
Lens Proof is made for site evidence in construction, insurance and motor claims, public works inspections, property management, legal work, and journalism.
PLANS
• Lens Core (one-time purchase): the camera, overlays, QR codes, and visual PDF reports.
• Lens Pro (subscription): adds AI reports and offline maps.
• Lens Trust (subscription): adds Content Credentials and trusted timestamps to Pro.
Each device gets one free 14-day trial of Lens Core. After the trial, choose a plan to keep capturing.

TL;DR: In Auto mode, Lens Proof now signs a video even when it can't reach the trusted timestamp service, for example when the cellular connection is weak or lost. With Require Content Credentials on, a video that can't be signed is now saved without Content Credentials instead of being lost.
IMPROVED
• Video Signing: With Timestamp Mode set to Auto, Lens Proof now signs a video even when it can't reach the trusted timestamp service, for example when the cellular connection is weak or lost. The video is signed without a trusted timestamp, as photos already are, and keeps its Content Credentials.
• Signing Status: When a file is signed without a trusted timestamp, the signing status now says that the file stays valid until the certificate expires.
• Require Content Credentials: The setting description now says that a capture may still save without Content Credentials if signing fails.
FIXED
• Videos: With Require Content Credentials on, a video could be lost when signing failed. Lens Proof now saves the video without Content Credentials instead.

• Require Content Credentials: The setting description now says that a capture may still save without Content Credentials if signing fails.
FIXED
