iPhone GPS timestamp camera · iOS 17+

Proof, on every photo.

SnapProof burns GPS, time, and address into every shot at the moment of capture. When a client says you didn't do the work, the photo settles it.

Why on-device matters.

Most "stamp camera" apps phone home. They upload your photos to compress them, run analytics, or sell the metadata. That works for selfies. It doesn't work for evidence.

Photos taken for work are sensitive. They show locations, faces, license plates, document text. They have legal weight. The chain of custody starts the moment the shutter fires — and SnapProof keeps it inside the iPhone.

  • No backend, no analytics SDK, no third-party tracker
  • The app talks to CoreLocation and Photos. Nothing else
  • If a cloud breach hits an evidence-camera company, your photos aren't part of it

Three taps from proof.

Step 1: Open — GPS timestamp camera workflow

1.Open

Launch straight to camera. GPS lock indicator turns green when ready.

Step 2: Capture — GPS timestamp camera workflow

2.Capture

Tap once. Timestamp, GPS, and address stamped instantly.

Step 3: Share — GPS timestamp camera workflow

3.Share

Send the stamped photo directly from your gallery.

Any job where "I was there" matters.

Field workers, contractors, drivers, inspectors, adjusters. Work where a photo without a timestamp is half the story.

What field pros ask.

Can I add a timestamp to iPhone photos after the fact?
Yes, but a back-stamped photo is not evidence. SnapProof writes the timestamp at the moment of capture, alongside CoreLocation GPS, so the stamp and EXIF agree. That is the chain of custody that holds up.
How do I add GPS coordinates to my photos?
Open SnapProof, grant Location permission once, then shoot. Coordinates render onto the photo pixel and write to EXIF. No menus to remember per shot.
Is the app free to start?
Free tier gives 5 stamped photos with every template. Beyond that, $14.99/year or $49.99 lifetime. No ads, no upsells inside the camera.
What is the best timestamp camera app for iPhone?
Depends what "best" means. SnapProof leads on on-device privacy plus lifetime pricing. Timemark has stronger team sync. Solocator is closest on raw GPS-photo. Full comparison here
How accurate is the GPS?
±3 meters typical in open sky, ±10 meters in dense urban areas. Uses CoreLocation kCLLocationAccuracyBest. If signal drops, the last known fix is used and noted in the stamp.
Does it work without internet?
Yes. GPS works offline. Address reverse-geocoding falls back to coordinates only if no network. EXIF, timestamp, and GPS still burned in.
Are the stamped photos tamper-proof?
The visible stamp is pixel-burned and can't be edited away without obvious damage. EXIF is preserved so forensic tools can verify. SnapProof does not add cryptographic signing. For legal admissibility, pair with a notary service if needed.
Can I use it for court evidence?
Courts assess photo evidence on chain of custody, not on the app brand. SnapProof preserves the conditions courts care about: original timestamp, GPS, unmodified EXIF, on-device capture. Pair with your own log of when and why you took each photo.
Does it drain battery faster than other cameras?
Slightly. CoreLocation runs while the camera is open. Closing the app stops GPS. In practice: a 30-minute field session uses ~3-5% battery on iPhone 14.
Is there an Android version?
iOS only for now. Android timeline depends on demand and dev capacity. Email to vote →
