The Problem
Lost Evidence
Photos deleted, forgotten, or gone with the team member. No proof of what was actually done on site.
Disputed Records
Someone says it wasn't done, delivered, or inspected. Without documented proof, it's your word against theirs.
Claims Denied
Without timestamped, location-verified evidence, insurance claims, lien filings, and compliance audits fall apart.

FAQ
Does it really work offline?
Yes, 100%. Photos, GPS, signatures, and crypto seal all work without internet. When you're back online, everything syncs automatically.
Is the proof admissible in court?
Yes. The cryptographic seal makes it tamper-proof. GPS timestamp proves location and time. Export format is ready for court and insurance.
What if my crew forgets to sync?
Data syncs automatically when they connect to WiFi. All data is cached locally and persists even if the app is closed.
Can clients sign on-site without WiFi?
Yes. Signature pad works completely offline. They sign right on the phone or tablet at the job site.
How much does it cost?
From £29/month for solo contractors to £99/month for teams. Try 14 days free, no credit card.
