Built Around Your Craft

An app that knows your trade.

You don't work like the next crew over, so your software shouldn't either. Both DeBe platforms reshape around your trade — CHERP changes what you see and the tools in your pocket, and SiteComm puts you in the room with the people who do exactly what you do.

Two platforms, your trade

Both apps fit the craft.

A pipefitter and an electrician don't do the same work — and they shouldn't get the same app. Across both products, your trade decides what shows up.

CHERP · The work

The tools you actually reach for

Your trade sets the terminology, the home-screen tools, the hazard and PPE prompts on your JSAs, the material list when you raise an MRO, and the field calculators in your pocket. 14 trade profiles ship today, with more generated on request.

SiteComm · The community

The crews who do your work

Your trade shapes who you talk to — guilds and brotherhoods for your craft, your local, and your apprentices. Ask the question only another tradesman in your craft can answer, and throw a shoutout to someone who earned it.

The 14 Trades

Find your craft.

Each profile reshapes the whole app around the way you work. Don't see your trade? We generate new profiles on request — the architecture spins one up on demand.

Pipe Trades

Plumbing, pipefitting — offset math, DFU, slope, thread engagement.

HVAC / Mechanical

Duct sizing, CFM, static pressure, BTU/load, refrigerant charge.

Electrical

Conduit fill, voltage drop, wire gauge, load and breaker sizing.

Fire Protection

Sprinkler layout, hazard prompts, and inspection workflows.

Carpentry / Framing

Stair rise/run, rafter length, board-feet, angle cuts, span tables.

Concrete

Volume for slabs, columns, footings; mix ratios; rebar spacing.

Civil

Grade/slope, compaction, earthwork, and site layout.

Insulators

Material lists and JSA content tuned to mechanical insulation.

Boilermakers

Heavy fabrication hazards, rigging, and confined-space prompts.

Ironworkers

Sling load, crane capacity, center of gravity, D/d ratio.

Sheet Metal

Duct fabrication, airflow conversions, and layout math.

Painters

Coverage, coatings, surface prep, and trade-specific JSAs.

General Contractor

Cross-trade coordination, daily logs, and crew oversight.

Safety Professional

Full safety suite — permits, inspections, incidents, muster.

What You Get

The whole app reshapes for you.

Pick your trade once and everything falls in line — the words, the tools, the hazards, the materials, and the people. Here's what changes for you.

Words That Fit

The app talks the way your craft talks — a "drop" means one thing to a pipefitter and another to an electrician, and your app knows which.

Tools Up Front

Your home screen surfaces the tools you actually reach for, in the order you use them — no hunting through someone else's menu.

Hazards Pre-Loaded

Your JSAs come ready with the real risks of your trade — silica, arc flash, rigging, confined space — so the paperwork keeps up with the work.

Your Material List

Raise an MRO and the items and units come from your trade's own catalog, not a generic dropdown that slows you down.

Your Brotherhood

In SiteComm, your trade puts you in guilds and crews with people who do your work — the right room for the question, the win, or the rough day.

Your Trade, On Request

Work a craft we don't ship yet? Tell us — the architecture generates a new trade profile on demand, built around how you actually run.

Math in the Pocket

Calculators tuned to your craft.

Every trade gets its own calculator set — offset and DFU for pipe, conduit fill and voltage drop for electrical, sling load and crane capacity for ironworkers, and more. All run fully offline. The full calculator lineup lives on the product page.
