Walkthrough · Pittsburgh, through August 2026

Every screen, in the order a watch commander would use them.

These are real screens from PatrolDesk running on Pittsburgh’s published data — 70,140 incidents over 32 months, through August 31. Every screen was captured from PatrolDesk on 23 September 2026. Nothing is a mockup.

Sit down. Know what to do.

Tonight, Where, the block in 3D, the watch order. Steps 01–10.

1:25

The right places. The right hours.

Staffing against demand, the watch model, the week by hour. Steps 04–07.

It went up. Say so.

Recording an order, the ledger, and a backtest that grades itself. Steps 09–11.

New to PatrolDesk? Start with the five-minute briefing for chiefs (5:21). Five more in the feature series: search and ask, the daily brief, Before You Go, game day, and clearance by arrest.

01 · TONIGHT

One question, then the right screen.

A first visit asks what you came to do — run tonight's watch, review an area, check an order, or take the tour — and opens there. It comes back each new session until you tick don't show this again. A share link never sees it.

The first-run choice: run tonight's watch, review an area, check an order, or take the tour
WHAT YOU’RE SEEING

Four tiles, one checkbox. Picking a tile is not a preference — it is the same as clicking that word on the rail.

WHY IT MATTERS

Nobody is taught a tool at roll call. The first screen has to make the next click obvious, and this one has four.

02 · TONIGHT

Tonight — the brief for the area you run.

Pick a zone and a category with the chips. The screen reads top to bottom: what changed, the next step, what always happens, whether the roster matches.

The Tonight screen for Zone 5: zone and category chips, what changed, next step, what always happens, whether the roster matches
WHAT YOU’RE SEEING

Zone 5, all categories, data through August 31. Five rising cells with their sigma; the top two on Friendship Avenue. 99 other cells are busy but not changing — and the screen says so. NEXT STEP is one button to the watch order, with the options and the cheapest cost already in the label.

WHY IT MATTERS

Every line is the same function the other screens use. There is no summary written by hand, so it can never disagree with the map.

▶ Watch this in “Sit down. Know what to do.” (1:46)
03 · TONIGHT

“Penn and Highland.” It goes there.

Type a corner, a block or a street in the Tonight box or the header and the map goes there with the records behind it.

After typing Penn and Highland: the corner marked on the map and the records within 75 meters listed
WHAT YOU’RE SEEING

Penn Avenue & North Highland Avenue: 10 reports within 75 m in the last 90 days against 4.5 typical — above typical — with the top types and the count since the data begins. Ask a question instead — burglaries in zone 5 last 28 days — and the answer is a computed sentence with the filters set to match.

WHY IT MATTERS

A commander who knows the city reaches for a corner in the first minute. This is the beat that decides whether they trust the rest.

▶ Watch this in “The Question in the Room” (1:33)
04 · WHERE

Where — what changed against its own history.

EMERGING scores every 150-meter cell against its own previous 84 days, seasonally corrected. The card that answers the question comes first in the column.

WHERE with EMERGING selected: fourteen rising cells for Zone 5 ranked by sigma, each with a LOOK AT THE BLOCK button, and the map colored by change
WHAT YOU’RE SEEING

Zone 5: 14 cells running hotter than their own history, ranked by sigma, each with a LOOK AT THE BLOCK button. The map shows rising cells in red, steady in gray, falling in blue.

WHY IT MATTERS

A permanently busy corner is not news. A quiet one that went from one to seven is. This screen finds change, not volume.

05 · WHERE

Every number explains itself.

Click any place and the reading is a computed sentence — which offenses, what hours, how tightly grouped — with the records listed underneath.

An emerging cell's drill-down: the computed reading, offense and day breakdowns, and the records themselves
WHAT YOU’RE SEEING

The finding, then the offense mix, the hours, the day of week, and every record with its date and type. Click a record and the map goes to it.

WHY IT MATTERS

When crime statistics are argued about in public, the argument ends at the records.

06 · WHEN

When — pattern or spike.

Day of week by hour of day, for everything in view, with the whole width of its own screen.

WHEN: the map above and the day-of-week by hour-of-day matrix below, with the busiest window named
WHAT YOU’RE SEEING

Zone 5's busiest window is Monday 16:00–17:00. Click a square and it says how many of that weekday actually carried records: a standing pattern, or one bad night.

WHY IT MATTERS

Thirteen of thirteen Mondays is a standing problem worth a standing response. Thirty-four records on one night is already over.

07 · STAFFING

Staffing — are your people on when the work is?

Demand by hour against the roster by hour, as shares, with an editable watch model.

STAFFING: demand by hour against the roster by hour for Zone 5, with the editable watch model
WHAT YOU’RE SEEING

35% of the work falls between 08:00 and 14:00, when 20% of the roster is on. Between 02:00 and 08:00 it inverts. The three-watch model is a placeholder — edit it live and the finding recomputes, per zone and per sector.

WHY IT MATTERS

For a department that is short, the schedule is the only capacity in the building that costs nothing.

▶ Watch this in “The right places. The right hours.” (1:25)
08 · ORDERS

Orders — what to do about it, costed.

HOLD, CONCENTRATE, SATURATE: places, surge window, the dose, the effect range from published trials, and how long until a reduction that size is measurable.

ORDERS: HOLD, CONCENTRATE and SATURATE for Zone 5 with cost, places, window and weeks to measure
WHAT YOU’RE SEEING

Zone 5, all categories: HOLD 5.4, CONCENTRATE 14.4, SATURATE 28.8 officer-hours a week, 13:00–18:00. One rising place left off because its dominant record is drug equipment — the card says so.

WHY IT MATTERS

The line nobody else prints is the last one: whether you will be able to tell it worked. Run the ones you cannot prove because the reasoning is sound, not because you will be able to show it.

09 · ORDERS

One page a sergeant reads at roll call.

When, dose, cost, the numbered places with sector and evidence, Before you go, the places seen, what to expect, and one button that records it.

A watch order: when, dose, cost, six numbered places with 3D buttons, Before You Go, the places seen
WHAT YOU’RE SEEING

Six places; each with a LOOK AT THE BLOCK button. Before you go: Penn Avenue has 16 weapons, aggravated assault and robbery reports on record since 2024; Frankstown Avenue 13, including a homicide. The camera column reads none known until the department loads its own list.

WHY IT MATTERS

Recording the order is what makes the review a measurement. Nothing about a recorded order can change afterward.

▶ Watch Before You Go in “Before You Go” (1:26)
10 · ORDERS

The block, in 3D, with the records on the buildings.

One button on any place opens Google Photorealistic 3D with every record in the window drawn where it happened. Hover any mark and it says what it is.

Look at the block: photoreal 3D with records on the buildings, the cell outlined, spots counted, and a tooltip open on one spot
WHAT YOU’RE SEEING

The cell outlined; records colored by category, the last 28 days ringed in white; spots counted ×N. The tooltip on one spot: 5 reports within 40 m, 2 in the last 28 days, most often around 11:00, 25 here since 2024. The panel beside it: the finding, where to stand, the busiest hours, the officer-safety line, the camera line, the most recent records.

WHY IT MATTERS

A sergeant recognizes a corner faster than an address, and a corner with its records on it faster still. Click a spot and the camera goes there.

11 · LEDGER

An order is a claim only if it was written down first.

Recorded orders are graded when the next month's data lands, against the places' own history, ring included. Backtests show what places do on their own.

The ledger: the July 31 backtests graded against August, and the camera list loader
WHAT YOU’RE SEEING

The July 31 SATURATE backtest graded against August: +43%, z 3.2 — “It went up. Say so.” Ring +28%, flagged. No deployment happened; this is the control every real order is compared against.

WHY IT MATTERS

A tool that admits a null result is a tool whose positive results can be believed. Everything in the ledger stays in the browser and exports to a file.

▶ Watch this in “It went up. Say so.” (1:30)
12 · MORE

“Is this summer worse than last summer?”

Two areas side by side, or one area against the same dates a year earlier.

Compare: Zone 5 violent, this summer against last summer, side by side
WHAT YOU’RE SEEING

Zone 5 violent, 3 June – 31 August 2026 against the same dates in 2025: 248 vs 222, +12%. Simple assault 96 vs 92, aggravated assault 45 vs 35. Counts, not rates; a year apart removes the season.

WHY IT MATTERS

The question every chief is asked in public, with the arithmetic under it.

▶ Watch this in “The Question in the Room” (1:33)
13 · TONIGHT

Dashboards don't get used. Briefs get read.

One page per area, per watch, printed from the Tonight screen in one click.

The daily brief for Zone 5, 06:00–14:00 watch: since the last brief, what changed, the watch list with near-repeat windows, the standing pattern
WHAT YOU’RE SEEING

Since the last brief, what changed, the watch list, the hours, and the records behind every line — for one zone and one watch.

WHY IT MATTERS

A printed page reaches the people a dashboard never will.

▶ Watch this in “The Page at Roll Call” (1:23)
14 · TONIGHT

Three minutes, eight screens, real numbers.

TOUR at the bottom of the rail drives the real screens with a spotlight and a caption, in the order a chief would ask for them.

The tour's first step: a spotlight on the Tonight header with a caption
WHAT YOU’RE SEEING

Each step opens the actual screen — not a slide of it — and says in two sentences what it is for.

WHY IT MATTERS

A demo you can hand to someone. Or take yourself, at 2 a.m., without anyone watching.

15 · ANYWHERE

The same tool, one hand.

The rail folds into a tab bar; the map fills the screen; the findings live in a sheet you drag between three heights.

The Tonight screen on a phone
The Where screen on a phone: the map full-screen and the findings sheet at rest
WHAT YOU’RE SEEING

Tonight as a single column with the zone and category chips at the top; WHERE with the map full-screen and the sheet at rest below it.

WHY IT MATTERS

A commander in a car gets the same analysis as the desk, with nothing hidden behind a layout that assumed a monitor.
