How it works
A phone, walked around the aircraft.
You walk around the aircraft as always, filming with your phone. One tap on Done, and the record is sealed when it reaches the server. Nothing to mount on the stand, nothing to integrate.
-
01
Choose the aircraft
Home is the list of your aircraft with the history of their walkarounds. Pick one and tap Start walkaround.
-
02
Walk around it
During the walkaround you see only the camera and the time. When you have walked all the way around, tap Done.
-
03
Get the proof
The record uploads by itself, even with the phone locked, and is sealed when it arrives. Share it as a link or a PDF report.
What the record proves
The walkaround happened. Here is who, when and where.
Sealed together with the video. The record does not judge the condition of the aircraft and does not replace the inspection required of you.

The part that matters
Sealed. Verifiable without us.
A separate verifier answers VERIFIED or TAMPERED. Every later change to the record is detectable, by anyone, without us.
VERIFIED
The record is exactly as it was when sealed.
TAMPERED
Something changed after sealing, and the verifier says what.
In the app today
Made for clubs, flying schools and aircraft owners.
Registering in the app creates your organisation, whether it is a club of thirty members or you with one aircraft.
-
Five walkarounds free
A new organisation has five walkarounds free, each up to 30 minutes.
-
History of every aircraft
Each walkaround is written into the history of its aircraft: when, where and by whom.
-
Members and roles
Invite members by email, each with a role. Their walkarounds belong to the club, not to the phone.
-
Built for the ramp
The upload finishes even with the phone locked, and after an interruption the recording carries on.
-
Share without an account
Send the proof as a link that opens in any browser, or as a PDF report.
-
Console for the admin
Manage the club's members, aircraft and records on a computer at walkcheck.eu/console.
Airlines, ACMI, handling, rentals
The walkaround is yours. So is the dispute.
Three companies at the aircraft, a signed walkaround, and then a mark on the fuselage. A sealed record shows what was in front of the camera, and when, not what someone remembers.
Ramp Evidence Week
Five days on your ramp, one written report.
One aircraft type, one team, sealed walkarounds on phones. You get every record and a written summary of what the app covers today, and what it does not.
Where this goes
The walkaround is only the beginning.
Each version starts as a direction and becomes a feature once people at the aircraft have tried it.

Questions
Short answers.
Does Walk‑Check replace the pre-flight inspection?
No. It records that the walkaround happened and seals it as evidence. It does not decide on the condition of the aircraft and does not replace the required inspection or the technician.
What does it cost?
A new organisation has five walkarounds free, each up to 30 minutes. Further walkarounds are charged under the contract with the organisation, or under a price list we email before the first invoice. Invoices arrive by email; nothing is bought in the app.
Who can verify a record?
Anyone you send it to. The link opens in any browser, without an account and without the app, and the verifier answers VERIFIED or TAMPERED.
Why do I have to verify my email first?
Until your email is verified, the Start walkaround button stays locked. Without a verified address the record would not be evidence.
What about people in the video?
The server blurs anyone whose face is visible, in a copy of the video. Only the blurred version can be played and shared; the original is kept and only Walk‑Check has access to it. Blurring is not yet guaranteed to catch everyone.
Is it for airlines and handlers too?
Yes. For airlines and handlers we set up the organisation, aircraft and people together with you; your team then downloads the app. More on the For operators page.
