Two apps, one job

How the pieces fit: what lives on the desk, what lives in the pocket, and the handful of ideas the whole product is built on.

The desk lives at app.getblt.ai in a browser. Jobs get set up there, the week gets planned there, the money lives there. It’s a keyboard tool — best on a laptop, good on an iPad, readable on a phone when you need it.

The crew app is BLT for iPhone. It’s built for someone standing on a slab with one free hand: photos, the clock, receipts, and what you’re on today. It is deliberately not a small version of the desk. Four things, done fast.

Photos and hours flow up from the app. Assignments and decisions flow down from the desk. Nobody re-types anything.

Sitting across both is @blt, which reads every photo as it lands, watches the budget, and answers questions about the job in plain English.

The spine

The spine is a job’s main page — what you open when you want to know where something stands. One scrolling thread, with anything needing a human decision pushed to the top.

The line

A single track across the top showing planned burn against actual built progress, with markers for today and for forecast completion. Under it, the facts in plain text: what day you’re on, what percentage is built, and the current completion date — with how far it’s slipped, if it has.

Four panels

Four buttons sit under the line. Each opens a slide-over panel, so you never lose your place.

PanelWhat’s in it
BuildEvery phase with its completion and, crucially, where that number came from — a person said so, counted from photos, or an estimate. Controls to assert a percentage, mark a phase done, or ask for a phase’s photos. Also the photo wall.
ProofThe shot list: photos the system has asked for, grouped by phase, with what’s in and what’s outstanding. Ask again, reassign, or waive a shot with a reason.
MaterialsEverything tracked, from needed through quoted, ordered, arrived, staged, installed. The gap between needed and ordered is the warning worth having.
SubsWho’s engaged, for what scope, at what number, and whether their insurance has lapsed. Each engagement is tagged labor, materials or turnkey, which routes their dollars into the right bucket.

How a phase gets to done

Four sources of truth, in strict order. A person’s assertion beats everything. Below that, counted photo proof — three of five shots in. Below that, an estimate, always labelled as a guess. And if none of those exist it says not established rather than showing a zero.

When a person’s number and the photo evidence disagree by a wide margin, the page says so out loud instead of quietly picking one. The person’s number still wins — they’re the one standing in the house.

One orange button

The product keeps a rule: the filled orange button is the single thing that most wants doing right now. Everything else is outlined. If you’re not sure what to attend to, look for the orange.

The week

Switch between The spine and This week from the top of any job. The week board is six columns — Monday to Friday plus a peek at next Monday — with three lanes: Work, On site, and Materials.

  1. Draft it @blt, draft this week reads your plan phase, the phase library’s task list, your regular crew, your subs, what materials are due and any inspection holds. On a job with no plan it says so rather than inventing one.
  2. Adjust it Adjust the draft opens @blt so you can talk to it in plain language. Anything it proposes arrives as a card you approve.
  3. Publish it Publish to the crew sends every rostered person their week in the app. Their marking it done is the acknowledgement.

Each block carries a readiness strip: whether enough crew are rostered, whether the material it needs will be there, and whether any inspection it’s gated on is actually booked. Computed live every time you look, never stored and left to go stale.

Money

A money rail sits at the bottom of every job screen — spent against estimate, what’s committed, what’s over. Opening the ledger expands the whole picture.

Four numbers per line: baseline (where you started), current (where it is now), committed (POs and awards out), and actual (money genuinely spent). A phase with no baseline shows a dash, never a fake zero.

Under that, every revision since kickoff — who changed it, when, and why. Every estimate change in the product goes through the same door and every one demands a reason. There’s no way to quietly move a number.

What lands on its own

What you do by hand

Sharing progress without sharing money

You can mint a read-only link for a homeowner, an architect or a sub — they see progress and photos in a browser with no login. No share link ever shows money. That’s enforced in code, not a setting anyone can fumble.

The thirteen phases

Every full build runs the same thirteen phases. They’re where the shot lists, cost benchmarks, inspections and durations hang. A renovation drops sitework, foundation and framing. A trade job narrows to that trade’s slice.

The percentages are the share of hard cost a phase typically represents — what your budget gets compared against when @blt tells you a phase looks light or heavy.
