Every facility, organized.

Create a site for each facility you support. Records, guides, L5X imports, and commissioning runs all attach to the right location. Status rolls up so you see at a glance which sites need attention — on mobile or the web dashboard.

Every fault, remembered.

Write a record once — fault, note, observation, or fix. Search it later by tag name, fault code, site, or the words you actually remember. Photos are OCR-indexed so text in your screenshots is searchable too.

Your crew, coordinated.

The web dashboard gives leads a real-time view of every commissioning run across the crew — who is working what, what passed, what failed, and what needs sign-off. Build templates, convert L5X files, and manage your organization from any browser.

Note: The web dashboard requires an internet connection. Field execution runs on the iOS or Android app, which works fully offline.

Every test, verified.

Build a commissioning template once — steps, assets, expected values, linked guides. Run it on every device of that type. Each result is stamped with who tested it, when, and what they observed. Fail requires a note. The run summary is your handover document.

Available on

One platform. Every device.

Mobile apps execute in the field. The web dashboard coordinates and designs from the office. All connected through the same account.

iOS — iPhone & iPad

The primary field tool. Write records, author guides, import L5X files, record voice notes, and execute commissioning runs — all from your iPhone or iPad.

✓ Fully offline — no signal required

All data stored locally on your device. Syncs to the cloud when connected (Pro + Team).

Coming Soon

Android

Full feature parity with iOS. Same offline-first architecture, same records, guides, L5X import, voice notes, and commissioning runs. Launching 6 months after iOS.

✓ Fully offline — no signal required

All data stored locally on your device. Syncs to the cloud when connected (Pro + Team).

In Development

Web Dashboard

The desktop companion to the mobile apps. Design commissioning templates, convert L5X files, manage your organization, assign runs, and review results from any browser.

⚡ Requires internet connection

Field execution always happens on mobile. The web dashboard is for coordination and design, not field work.

The problem

Controls engineers lose knowledge
every single day.

Not because they are careless. Because the tools they were given were not built for a plant floor.

"I fixed this fault before."

You solved it in 2 hours last time. This time you spent 20 minutes, because the solution lived in Indulum.

The senior tech retires.

Twenty years of system knowledge. Every quirk, every workaround, every undocumented change. Gone in a Friday afternoon handshake.

No signal. No laptop. No problem.

You are in a massive concrete and steel building with no signal. TestRail needs a browser. OneNote needs the cloud. Indulum works offline on mobile — guides, records, and commissioning procedures exactly when you need them.

What Indulum does

Built for the plant floor.
Not the office.

Every feature designed around one constraint: it has to work when there is no signal, no laptop, and no time.

📝

Records That Stay Found

Write a record once. Search it by tag name, fault code, site, or the words you actually remember — even if the photo you took has the text in it. OCR indexes everything automatically.

Commissioning Checklists

Build a checklist template once for a device type. Run it on every instance on the job. Each run stamps who tested it, when, and the result — Pass, Fail, Hold, or Skip. Fail requires a note.

📂

L5X Import — Full Tag Intelligence

Import your Studio 5000 export on mobile or web. Indulum reads every tag, every alarm instruction, every rung comment. Your records link to real tag names. Your checklists populate from real I/O maps.

Studio 5000 · Allen-Bradley · Local Only

📖

Step-by-Step Guides

Author commissioning and troubleshooting guides with screenshots, tag references, and ordered steps. Share them as a single .indlog file. Read them on your phone as a second screen next to the panel.

.indlog Format · AirDrop / Email · Offline Reader

🎙️

Voice Notes, On-Device

Record what you are seeing hands-free while still in the panel. On-device transcription only — audio never touches a server. Works in the dead zone. Transcript is searchable the moment you stop recording.

On-Device Only · Searchable · No Cloud

⚡

Fault Code Reference

Search fault codes offline. Link a code directly to a record or guide step. When you import an L5X, alarm instructions auto-populate your reference with real messages from your actual program.

Offline · L5X Auto-Populated · Severity-Coded

L5X Import

Your program already knows everything.

Studio 5000 exports your entire program as an L5X file — every tag, every alarm, every rung comment. Indulum reads it and makes that knowledge available everywhere in the app.

🏷️

Tag Database

Every controller and program-scoped tag with data type, description, and UDT member structure.

🔔

Alarm Instructions

ALMD and ALMA parameters extracted — message text, severity, and monitored tag — straight into your fault reference.

🔌

I/O Module Map

Every slot, module type, and channel assignment — available as a source when building commissioning asset lists.

🔒

Stays on Your Device

L5X files are your client's IP. Indulum parses locally on mobile or in your browser session. Nothing is uploaded to any server, ever.

The tools you were using were not
built for this job.

OneNote is a notebook. TestRail is a browser app. Neither knows what an L5X file is.

Controls Engineer

4 years · Fortune 500 support

BUILT ON

Package Handling facilities
Steel plants
Conveyor systems
Support calls at 2 AM

"I needed an app that remembered what I knew — not a generic notes app that made me do all the organizing myself."

Four years supporting a Fortune 500 company. Taking calls. Driving to facilities at odd hours. Fixing the same fault twice because the first fix lived in a notebook nobody could find, or in the head of the tech who left six months ago.

Every app I tried was built for someone else. OneNote did not know what a tag was. TestRail needed a browser and an IT ticket to set up. Notion was beautiful and completely useless at 2 AM in a panel room with no signal.

So I built Indulum. It knows what an L5X file is. It knows what a fault code means. It works when there is no signal. And it remembers everything — so the next time that fault shows up, the answer is already there.
