A maintenance manual you find on the machine
The same plan produces the PDF manual: it downloads from the station's QR code, prints when needed and speaks the language of the people at work.
Downloadable, printable, savable
Builder exports the maintenance manual as a PDF, numbered and dated with the same revision as the package, one copy per plan language.
Online on your website
Each station's QR code leads to the manual published on your website or portal. Your documents stay under your control and do not depend on an outside service.
Ready for paper
The manual is laid out for printing, with a cover, an overview of intervals, page numbers and the contact for requesting a paper copy.
In the language of the people at work
One plan with optional translations: technicians read it in their app language and the PDF comes out in every language you choose, with images at the exact point in the text.
From the line design to the technician's hands
Two tools, one package. No server, no subscription for app users.
Write the plan in Builder
On Windows you define stations and tasks: intervals in hours or months, instructions with inline images, materials and safety warnings.
Export package and labels
Builder produces a package signed with your company name, the PDF maintenance manual and the QR labels to apply to each station.
The technician works with Field
In the Android app they import the package, scan the QR code, read the procedure and log the job with hour meter reading, signature and PDF report.
Builder: write the plan the way you'd explain it
- Plain-language instructions with imagesPlace photos and diagrams exactly where they belong in the text and preview it the way the technician will see it.
- Due dates in hours and monthsEvery 2,000 h or every 12 months, whichever comes first.
- QR labels that lead to your manualOne per station. With the app it opens the procedure; with the phone camera it opens the page you choose.
- PDF manual in several languagesWrite the plan once and translate it where needed: each language gets its own manual, at the same revision as the package.
- Revisions with historyUpdate the plan, export a new revision, and the jobs already logged stay where they are.

Field: on the shop floor, even offline
- Time left, at a glanceFor every task the app shows hours left, expected date and status: on schedule, due soon, overdue.
- Mandatory, consistent hour readingsEvery job starts from the machine's hour meter reading. Inconsistent readings are flagged.
- Signature and PDF reportThe technician signs on screen and the app generates the report with the builder's logo.
- A history nobody can rewriteA job can be deleted within 24 hours; after that it's final.
- Five languagesFree, works offline, in English, Italian, German, French and Spanish.

A plan that can't be forged
When the technician imports a package, Field checks who it comes from and that nobody has changed it.
Signed by the company
Every licence has its own key. The package carries the signer's name and Field shows it next to the line.
Intact, file by file
If even one image is changed after export, the app notices and reports it.
With a trusted date
The signature gets a timestamp from an independent service, so you know when it was applied, even years later.
One licence per company, unlimited seats
Only those who write plans pay. Technicians use Field for free.
Annual licence
Per company, renewed yearly

What you've published stays yours
If the licence expires, plans already exported stay valid and readable forever; only new revisions stop. And if Linetrace were to cease trading, current licences become perpetual.
Frequently asked questions
Where is the PDF manual published?
On your website or document portal. You enter the address in Builder and it goes into the QR codes. Linetrace does not host your documents: how long they stay available depends on where you publish them.
Does the QR code work without the app?
Yes, if you have set an address: the phone camera opens your page. With the Field app the same QR code opens the station's procedure and its service history.
Do I need an internet connection?
No. Builder and Field work offline. The package goes from PC to phone as a file, for example by e-mail, cable or shared folder.
Which devices does it run on?
Builder runs on Windows. Field runs on Android phones and tablets with a camera to read QR codes.
How are the remaining hours calculated?
From the latest actual reading of the machine's hour meter. If a task has never been done, counting starts from the machine's hour zero. The expected date is estimated from average daily use.
What happens when I update the plan?
You export a new revision. The technician imports it and the history of jobs already logged stays intact.
Can I modify another builder's plan?
You can start from their package to create your own. It becomes a new line, signed by your company, showing which plan it derives from. The original is left untouched.
How many people can use Builder?
Everyone in your company: the licence has no seat limit.
How do I activate the licence?
You receive the program with the licence file and, separately, an activation code to enter on first launch.
Which languages are the programs in?
Builder and Field are available in English, Italian, German, French and Spanish, and each user picks their own language. You write the maintenance instructions yourself, in your technicians' language.
