The machine answers
Photograph the nameplate. The catalogue finds the model, its manual and the rules that apply to it.
Watch 20 secondsFor professionals · the field app
The field app with the machine’s manual on the order.
Orders, the van, hours and kilometres, and the manufacturer’s own manual, alarm codes and rules for the machine in front of you. Photograph the nameplate and the catalogue finds the model. Ask a question and get the page. AI structures. The technician decides.
In daily use on real jobs since September 2026.
In the van
What the catalogue looks like in a technician’s hand.
Three screens from the app in production. The catalogue answers the technician standing in front of the machine, with the page it is written on.
Ask the manual
Pre-charge, fuse size, page number. When it is not in the sources, the app says so instead of guessing.

Discontinued part
Photograph the label. If the part is discontinued, the catalogue shows the documented successor and where that is written.
Watch 20 secondsAll nine screens, the command field and the app itself, on Google Play and the App Store, are on the field app page.
Why
The manual was always somewhere else.
The order is in one system, the manual is a PDF on a laptop in the van, the alarm code is a search on the phone, and the hours are written down on Friday from memory. Every job starts from zero.
The manual nobody has open at the machine
The alarm code nobody remembers from last time
The hours nobody wrote down
The catalogue
One catalogue behind the app.
Manufacturer manuals, alarm codes, manufacturer rules and documented successors live in one catalogue. The app sends it what you have, a photo, a code or a number, and gets back what is written, with the page it is written on.
A photo, a code or a number comes in
The catalogue identifies the machine or the part
What is written is shown with its source. A person decides
The machine
Photograph the nameplate. The catalogue finds the model, its manual and the rules that apply to it, and they stay on the order for the next visit.
The alarm
Type the code. The manual’s causes are listed in the manual’s own order, you tap the one it turned out to be, and the app shows it the next time that code comes up.
The part
Photograph the label. If the part is discontinued, the catalogue shows the documented successor and where that is written. A candidate, not a guarantee.
The job
Orders with the client’s drawings and revisions, parts taken from the van, hours and kilometres per day. No prices in the app: time and material are measured first, your price list is applied afterwards.
Your organisation, your orders, your van.
Set up your organisation and invite your technicians. Orders carry the client’s drawings with revision, the parts taken from the van, the hours and the kilometres per day, and the manual for the machine on the order. Organisations are kept apart: you see your own orders only.
In front of the machine with the catalogue in your hand.
Photograph the nameplate and the catalogue finds the model, its manual and the rules. Ask it a question and get the page. Type the alarm code and see the manual’s causes, and what it turned out to be last time. Type one word at the top of the order and the right panel opens: photos, hours, travel, materials.
A reviewed case becomes your order.
A firm set up to receive Describe cases sees the reviewed ones in the app, and the technician who takes one gets the customer’s text, the reviewed case and the photos on the order. Nothing is assigned automatically.
The same catalogue, elsewhere
Where the catalogue is also used.
The catalogue behind the app also answers three services that run on their own addresses. They are not part of this site; the links go straight to the apps.
Describe
A tenant or property manager describes a problem with a photo. AI structures it, a professional reviews it, and the customer gets a written case. A firm set up for it can take the case in the field app.
describe.beeping.me →PartSignal
A photo or a number of a part. The catalogue identifies it and, if it is discontinued, shows the documented successor. Paid per search. A candidate, not a guarantee.
app.partsignal.parts →Material Inventory
Parts documented with a photo before they are removed or written off. Technicians register them from the van, inside the field app.
inventory.partsignal.parts →Where you log in
One door, described as it is.
Only the service firm’s own members log in to the field app: owner, admin, technician. There is no public sign-up and no customer portal. We set up your organisation; your technicians log in with their own accounts, on Android, iPhone or in the browser.
Owner and admin
Set up the organisation, invite technicians, see every order and the van.
Technician
Own account, own orders, the van and the catalogue in the pocket.
New firm
By request. We set up your organisation, your technicians, your van. Organisations are kept apart.
No prices in the field app: time and material are measured first, price lists come after.
