Why Knurl

You're caught between two bad options.

Knurl is built for maintenance teams who work on the floor.

Priced for one facility, not one user. Designed for the phone, offline-first. A printed sticker is all the hardware.

What changes for you

Four promises. Not features.

Knurl is built on four things we think matter to a maintenance team. They run on every tier — from Starter to Enterprise.

The scanner is already in your pocket.

Stick a QR sticker on every asset. Scan to start a job, scan to report a fault, scan to log a service. Works on any phone — no beacons, no gateways, no RFID.

Zero hardware beyond a printed sticker

Photo proof or it didn't happen.

The app literally won't let a technician tap done without a photo. Every state transition is signed and timestamped — ready to show at the next inspection, not just trusted in standup.

Append-only audit trail · every tier

Offline-first by design. Syncs when signal returns.

Built with an offline-first design: the mobile app is designed to keep assets, work orders and photos on the phone. When signal returns, photos sync first, then updates — never silently overwriting anyone else's work.

Idempotent sync · no data loss

Assignments arrive on WhatsApp. The work happens in Knurl.

Managers tap Invite technician — a one-time link lands on WhatsApp, OTP, done. Assignments and approvals are sent on WhatsApp too. The technician opens the Knurl app for the actual scan, photo and close.

WhatsApp + email · no per-user fee
How it works

One loop. Five steps. Built for the floor.

A maintenance program is a loop — find the asset, do the work, prove it. Knurl is designed around that loop, instead of around report-builders and module trees.

App installed: the work order opens straight away. Plain camera: a public asset page with a link to download the app.
01
QR sticker
Stick it. Forget it.

Each asset gets a QR sticker generated inside the app. Print, stick, scan. No special scanner; the phone camera is the reader.

02
Scan
Point the camera.

Your team uses the Knurl app. Anyone else with a plain camera just gets a public asset page with a link to download the app.

03
Work order
Start or report.

Open the assigned work order. Or raise a new issue against the asset — managers triage it from the dashboard.

04
Photo proof
Can’t tap done without it.

The app won’t let a job be marked done without at least one photo. Proof of work is built in, not optional.

05
Sync
When the bars come back.

Work done offline is designed to sync automatically as soon as the phone is back online — photos first, then the updates. No work gets lost; no edit is silently overwritten.

Every change is logged: who did it, when, why. Nothing is overwritten or quietly edited.
What managers see

The command surface, not another feature list.

Four screens for a manager’s everyday work in Knurl. Home — is anything on fire? Work orders — triage and assign. Each order — a signed audit trail. Analytics — what the week actually looked like.

Home — “Nothing on fire. 7 open.”
Work orders — triage, assign, review.
Each order — every step, signed, never overwritten.
Analytics — projections over the event log.

01
Hotels
Guest reports turn into work orders. Engineering picks them up on the app, fixes them, snaps a photo, closes them. The GM sees the week’s count without asking a single person.

02
Factories
Downtime is dollars per minute. QR every machine. Run preventive schedules so things break less. When they do, the right tech is on it before the line is cold.

03
Clinics & healthcare
Biomed and building, one inbox. For clinics, day-surgeries and small hospitals. Every fix recorded with who, when, what, photo. Cleaner records — without an enterprise rollout.

Start your 14-day free trial

Move from a messy group chat to work orders with photo proof — no credit card.

For building managers and engineering heads:

  • Proof for every fix. A technician can't mark a job done without at least one photo, and work-order status changes record who made them and when, with notes or reasons where required.
  • No extra scanning hardware. Stick a printed QR sticker on each asset; the phone camera is the scanner.
  • Designed offline-first. The technician app is built with an offline-first design and is designed to sync when signal returns. No per-user fee on any plan.

How the trial works

  1. Sign up and create your facility (email + password, no card). Import your asset list from a spreadsheet or add assets one by one.
  2. Print the QR stickers and invite your technicians. Enter their name and phone number, then share the invitation link via WhatsApp.
  3. Run your first work order. The tech scans, fixes, photographs, closes — you see it on the dashboard.

Everything you also get

The product grows with you.

The core loop covers the day-to-day. These are the capabilities you'll reach for once it's running — already part of the product, not bolt-ons. The tier badge on each row tells you when it unlocks.

Preventive maintenance
Recurring schedules on time or meter — so things break less. PMs land in the same queue as anything else.
Team+
Custom checklists
Per-job inspection lists attached to a PM template. Tick boxes, capture meter readings, log condition notes — all signed into the audit trail.
Team+
Recurring work orders
Non-PM repeating tasks (cleaning rounds, weekly walks). Same engine as PM, different framing.
Team+
Spare parts inventory
Stock counts that decrement themselves when a part is used on a job. Low-stock alerts go to managers; asset service history shows what's been replaced.
Team+
Time-on-job tracking
Per-technician clock from work-order start to close. Aggregates into reports — who closed the most jobs, who's slowest on which asset.
Team+
Vendor directory + assignment
Vendors per asset and per category. Contract documents and contact details one tap from the asset record.
Operations+
Purchase orders + receive flow
Raise a PO from a low-stock alert or a work order, receive it (auto-decrements inventory), close it.
Operations+
Approval workflows
High-priority or high-cost work orders pause for an approver. The approver gets notified on WhatsApp; the audit trail records the decision.
Operations+
SLA timers
Reactive work orders count down from the SLA you set. Yellow at 75%, red at breach — visible on the queue, surfaced in reports.
Operations+
Public API + HMAC webhooks
REST API with bearer-token auth scoped per key, plus outbound webhooks (HMAC-signed, retry with backoff). Same interface our own dashboard uses.
Operations+
Location hierarchy
Floors, zones, rooms within a facility. Filter the queue by location; print sticker batches per zone.
Operations+
Roll-up reporting
Open work orders, total cost, longest-open age — all aggregated across every facility in the account.
Portfolio+
Site benchmarking
Which facility has the worst MTTR? Which is blowing its budget? Compare sites side by side.
Portfolio+
Cross-site templates
Define an asset class or a PM schedule once; apply it at every facility. Updates propagate.
Portfolio+
Per-site permissions
Regional managers see only their region. Site managers see only their site. Head office sees everything.
Portfolio+
Facility budgets
Per-site annual budget; reports show budget vs actual rolling. Forecast burn-down by month.
Portfolio+
Custom roles
Granular custom roles beyond owner/admin/manager/technician. Scoped + delivered during Enterprise onboarding.
Enterprise+
Custom retention
Set your own retention policy (e.g. 7-year work-order retention).
Enterprise+
Custom ERP integration
REST API + HMAC webhooks scoped + built during onboarding to push WO events, asset changes and PO receipts into your accounting/ERP/finance system. We do not ship named-vendor connectors out of the box.
Enterprise+
IoT sensor ingest
Bring your own temp, pressure, runtime sensors. Threshold breaches auto-create work orders. Scoped at Enterprise onboarding — we look at your sensor protocol and wire it through during setup.
Enterprise+
Predictive maintenance
Failure-pattern insights from your repair history. Activates per-asset once that asset has enough closed reactive work orders for the model to learn from — no fake suggestions on day one. Enabled at Enterprise onboarding once your history meets the threshold.

FAQ

The questions everyone asks first.

The app is built with an offline-first design: it is designed to keep a copy of your facility's data on the phone so a technician can carry on without a connection. When the signal comes back, photos sync first, then the updates. Edits made offline are never silently overwritten by someone else's.
We don't delete your data because you forgot to renew. When your subscription ends, whether you cancel or a renewal payment fails, you keep full access until the end of the period you paid for, then 7 days at full function. After that the app goes read-only for 180 days: everything stays viewable and CSV export keeps working on your plan, but nothing new can be created or updated. If you still haven't renewed, the facility may be deleted 90 days later. If a payment is refunded or charged back, the account goes read-only straight away.
Your plan is limited by asset count, not by people. Starter caps at 10 users; Team, Operations, Portfolio and Enterprise are all user-unlimited. Invite the night shift, the seasonal crew, the on-call subcontractor — the price doesn't change.
No. The only physical artifact is a printed QR sticker. The phone is the scanner — your team already has one. Scanning with the Knurl app opens the asset offline; scanning with a plain camera opens a public asset page with a link to download the app.
You do. Your facility owns the asset registry, the work-order history, the photos, the audit log. We're the system of record; you're the principal. If your subscription ends without a refund or chargeback, whether you cancel or a renewal payment fails, everything keeps working until the end of the period you paid for, then 7 days at full function. After that your data stays viewable in read-only mode, with CSV download for export, for 180 days, and then the facility may be deleted 90 days later. If a payment is refunded or charged back, the account goes read-only straight away.
Day 1 morning: sign up, create the facility, import your asset list (CSV or one at a time). Day 1 afternoon: print stickers, walk the building. Day 2: invite your technicians. Day 3: your first real work order goes through the app. No consultant, no IT ticket.
The 14-day trial is the demo — the Team plan, full app, real data, no card required. If you'd rather walk through it together, write to us and we'll arrange a call.
No new login. The manager taps Invite technician on the dashboard; a one-time link arrives on WhatsApp; the technician opens it, enters the OTP, and they're in. The same WhatsApp channel also sends assignments and approvals. The technician opens the Knurl app for the actual scan, photo and close.
Each device has its own ID. From the dashboard, revoke the device or remove the user — the next time that phone reaches the internet it receives the signal and wipes its local copy. Their offline edits up to that point are still in the audit log.
