Proof-of-work camera + team console

Verifiable proof photos for work that happens on site.

ProStamp stamps every field photo with a trusted timestamp, GPS, and street address — sealed with a tamper-evident signature. Your office reviews, verifies, and delivers it all from one console.

ProStamp photo stamped with time, GPS, and street address

Built for evidence, not decoration.

Every photo carries the proof a client, insurer, or auditor needs — captured the moment work happens, impossible to backdate or fake.

How it works

From the field to the client in three steps.

01

Capture

Open the app and shoot. ProStamp burns in the time, GPS, and street address, then seals the photo with a cryptographic signature.

02

Auto-upload

Photos sync to your team’s secure cloud the moment there’s signal — no manual export, nothing lost on a lost phone.

03

Review & deliver

Managers review by job, confirm authenticity, and export clean reports for clients and claims.

One system, two jobs

Made for the people in the field and the people in the office.

For field teams

A camera that does the paperwork for you.

Crews just point and shoot. ProStamp handles the proof — even with no signal.

  • One-tap stamped capture
  • Works offline, syncs automatically later
  • GPS coordinates and street address baked in
  • Your company logo watermark on every shot
