It all started with a shared frustration. How many times have we searched through hundreds of scattered photos on our phones for that specific image of a wall’s condition before work began? How many reports have we written by hand, painstakingly copying information that a tool could have compiled automatically?

We looked for a solution. We tried several. None really matched our needs: too complex, too expensive, too focused on a single trade. So we decided to create the one we wished we’d found.

An App Built for Those Who Build

ProjectProof is designed for everyone who undertakes real projects and needs to document them. Not just construction professionals, though we thought of them first. The contractor renovating a kitchen, the amateur gardener tracking their vegetable patch, the motorcycle enthusiast restoring a vintage bike, the artist documenting their creations: all share the same fundamental need to keep a structured record of their work.

Our ambition was simple: create a tool that adapts to your projects, not the other way around. A tool powerful enough to meet a site manager’s demands, yet intuitive enough for someone who’s never used a professional application.

What ProjectProof Lets You Do

Visually documenting every stage of your projects becomes natural. The app organizes your photos by categories — initial state, work in progress, final result, technical details — and automatically attaches useful metadata: date, time, GPS coordinates. No more digging through your gallery to find the right image.

Project information management centralizes everything you need: descriptions, dates, projected and actual budgets, list of stakeholders. You always know where things stand, without juggling multiple apps or notebooks.

The integrated electronic signature transforms your assessments into contractual documents. Get a condition report, work acceptance, or quote approval validated directly on the touchscreen. The document is timestamped and locked against any subsequent modification.

Professional report generation automatically compiles your photos, notes, and signatures into a PDF or HTML document ready to send. Add your logo and contact details for a result that reflects your professionalism.

Your Data Stays Yours

In a world where our personal information often circulates without our consent, we made a clear choice: ProjectProof stores all your data locally, on your device. No automatic synchronization to remote servers, no tracking of your usage.

This choice means some responsibility on your end — remember to regularly back up your important data — but it guarantees that your projects, photos, and client information will never leave your phone without your explicit decision.

Free, With No Compromise on Features

ProjectProof is completely free. All features are accessible from download, with no trial period or artificial limitations. Generated reports simply carry a “Generated with ProjectProof” mention — our only request in exchange for a complete tool.

Available on iOS and Android

The app works on Apple smartphones and tablets (iOS 13.0 and later) as well as Android devices (6.0 and later). The interface adapts to your screen size for an optimal experience regardless of your device.


We created ProjectProof to solve our own problems. We hope it solves yours too.
