FIG. 01 Campaign order taking, shared iPad
The Workspace order pad on a landscape iPad: campaign products as tap targets with quantity steppers, and an order rail holding the customer, collection date and confirmed lines.
Captured from the working product, not a mockup. Designed for quick, calm use at the counter.
01 / Purpose

Capture it once.
Use it everywhere.

Workspace replaces handwritten campaign books and repeated admin with one dependable source of truth for the shop floor and back office.

02 / Context

Independent food retailers hold a surprising amount of operational knowledge in paper notebooks, spreadsheets and memory. Christmas pre-orders make the problem visible: the same information is written, counted and checked several times.

The product had to feel quicker than paper, work on a shared iPad in a busy shop, and still produce useful prep, collection and compliance outputs.

FIG. 02 Two changes due, dated and counting down
The PaperWatcher home page: two price changes due in the next fortnight, each dated and counting down, above the national title list with the changing titles flagged.
Captured from the running product. Free, no account, nothing sold.
01 / Purpose

A price change
is never one change.

“The newspaper price is changing on Monday” sounds simple. It has to reach the EPOS, the shelf labels, the ordering system and the staff before a customer is charged the wrong amount.

02 / Context

Newsagents and independent retailers historically tracked this by hand: trade emails, spreadsheets, and someone remembering. Miss an update and you get till discrepancies, corrections, and a customer who trusts you slightly less.

The data existed. What was missing was somewhere to look it up quickly, see what is coming, and act before Monday.

The Sun on PaperWatcher: a price rise due in 13 days listed for each of the six publishing days, the current price and barcode per day, and a stepped chart tracking weekday and Saturday prices from 90p to £1.85.
Title recordWhat is about to change, what it costs today, and every step that got it there. Weekday and Saturday tracked apart, because they move apart.
The State of the Trade analysis: a line chart of the average cover price by month, risen 71p since November to £2.44, above a histogram grouping active titles into 50p price bands.
State of the TradeEvery figure and headline derived from the event log, so the analysis rewrites itself as data lands.
The Retail Tools index: a searchable toolbox of calculators and file utilities for independent retailers, each labelled with whether it runs locally or uses PaperWatcher data.
Retail Tools87 free utilities, each labelled with exactly where your data goes.
05 / Contribution

From a data problem to a public service.

Product directionTurned a recurring trade annoyance into a service with a clear, narrow promise.

Data designModelled prices as dated events so history, barcode changes and audit trails all fall out of one store.

EngineeringBuilt the ingest pipeline, alerting, exports, JSON API and a toolbox of 87 retailer utilities.

OperationsRuns as one process on one small server, with streaming off-site backup and loud failure modes.

FIG. 03 Deciding, planning, remembering
The Our Little Life home screen, asking “Right then. What are we doing?” above large choices: decide for us, what should we eat, get us out of the house, stay-in night.
The decide screen after choosing energy and indoor or outdoor: four suggestions drawn from the household’s own list, each with a single “We’ll do this” action.
The food plan: a week of meals on one shelf, each meal carrying its ingredients, with a control to push them onto the shared shopping list.
Captured from the running product, with invented household data. Built for the phone in your hand on a Tuesday evening.
01 / Purpose

Not another
chore list.

Most household apps open on everything you have failed to do. This one opens on a question worth answering: right then, what are we doing? The admin still exists, but it waits its turn.

02 / Context

Two people, one household, and the same small negotiations every week: what to eat, whether to go out, whose turn it is to ring the dentist. None of it is hard. All of it is friction, and most of it is decided while tired, on a phone, in the ten minutes before something else starts.

So the product is phone-first rather than phone-compatible, and it leads with a decision rather than a backlog.
