Proof Photo

Features
Read full description

Proof Photo is a verification camera that stamps every photo you take with an authenticity badge — including the exact timestamp, your location, and the device model. Photos are shared directly from the camera and are never saved to your device, ensuring they cannot be modified. Perfect for situations where you need to prove a photo is real and unedited: insurance claims, property inspections, delivery confirmations, workplace documentation, or any time someone needs to trust that what they see is what actually happened. HOW IT WORKS 1. Open Proof Photo and take a photo. 2. The app automatically stamps the photo with a verification badge: date & time, city & country, device model, and an authenticity statement. 3. Share the photo directly via Messages, Email, WhatsApp, or any app — it goes straight from the camera to the recipient. KEY FEATURES • Verification badge with timestamp, location, and device info • Photos are never saved locally — sent directly from camera • Front and back camera support • Pinch-to-zoom and tap-to-focus • Flash control (auto, on, off) • Clean, intuitive interface • No ads, no tracking, no accounts • 5 free photos included • One-time $2.99 purchase for unlimited use YOUR PRIVACY Proof Photo collects no data. No analytics, no tracking, no accounts. Everything happens on your device. The only external service used is Apple's geocoder to convert your GPS coordinates into a city name for the badge.

Read full description

TaskStamp is the professional timestamp camera built for contractors, property managers, and field service teams. Capture verifiable proof of work with accurate time, GPS location, a live street GPS map, weather data, and your custom company logo stamped directly onto every photo.
