Timestamp Camera
Time, place and a note on every photo.
A camera that stamps the time, place and a note on every photo, and signs each one so it can be checked later.
Screenshots
Captured in the iOS simulator, which has no camera, so the viewfinder shows a test scene.
What it does
Works like the iPhone Camera
16:9, 4:3 or square, 0.5×, 1× and 2× lenses, pinch to zoom, tap to focus. A photo is taken only when you press the shutter or a volume button.
Time, place and note
Date, time and time zone, coordinates with their accuracy, street address, note and photo ID, burned into a full-resolution photo.
Your layout
Long-press the viewfinder to place blocks in nine spots. Start from a preset or save your own style.
Proof you can check
Each photo is signed with a key held in the Secure Enclave and added to a hash chain. The proof travels inside the file and can be checked in the app.
