“My signal is bad.” Now you can prove it.
NetProof measures your connection where you are, stamps every measurement on our server, chains and signs it, and hands you a weekly certified report with a public verification link to forward to the phone company.
check_circleWe open NetProof to new accounts in the order requests arrive.
Three steps. Nothing to install.
Register the device
Open NetProof on the phone or computer you want to prove; it registers itself, and you can invite another device with a QR code or a link.
Measure, once or every hour
Ten small requests for latency, jitter and loss, a 512 KB download and a 256 KB upload, battery, storage and where you were — and the server adds its own stamp.
Get the certified report
Every Monday a branded PDF of the week lands in your vault, with score, worst moments with GPS, what the server saw, hash chain, signature and a verification link.
Evidence, not screenshots
Stamped by our server
The server records the exact time, the public IP you came from, the company that owns that network and its own round-trip to your device.
Hash chain per device
Each measurement carries the hash of the previous one. Remove or edit one and the chain breaks, visibly.
Signed by our key
Every check and every report is HMAC-signed on the server, and the key id is printed on the PDF.
Public verification page
The link on the PDF recomputes the PDF hash, the report signature and the whole chain, and says VALID or NOT VALID. No account needed.
Compare your networks
Name each network once — home Wi-Fi, a hotspot, line A, line B — and see the speeds side by side. Hotspots are flagged when the connection leaves through a mobile carrier.
Where it was bad
GPS on every check turns the bad spots into evidence of coverage at a place and time.
Who it's for
Anyone with a bad connection
Measures at home or on the road and forwards the signed weekly report to the phone company.
Companies with people in the field
Invites each crew phone with a QR code, sees the dead zones on job sites and brings data to the carrier.
Anyone choosing between networks
Compares office Wi-Fi, a phone hotspot, line A and line B side by side and picks the one that actually works.
Start with one device, free
The Trial covers 1 device, 1 certified report and 200 checks a month. Prices for the other plans are announced at launch, and early-access accounts keep their devices.
Questions
Why not just a speed-test screenshot?
A screenshot proves nothing. NetProof adds our server's own stamp, links each measurement to the previous one and signs it, so anyone can check it was not changed.
Can it see my carrier and signal bars?
Not on the web: a browser cannot read them. The phone app, coming next, will add the carrier name, network type and signal, and keep measuring in the background.
How does someone check my report?
They open the verification link printed on the PDF. It recomputes the hashes, the signature and the chain and says VALID or NOT VALID, with no account.
Will my carrier accept it?
NetProof documents what your connection delivered at a place and time. Whether a carrier or regulator acts on it is their decision.
Who owns the report?
You do. It is saved to your DOCZ vault, and you decide when to share it with your company or forward it to the carrier.
Can a company measure every crew phone?
Yes. Invite each phone with a QR code; each device keeps its own chain, and the weekly report shows which devices had a poor week and where.
