Our role & approach
Design & app development — the app and its landing page, from structure and visual design to build and launch.
Live since 2026.
Key features
What’s in the app.
Today’s focus
The dashboard lists the day’s scheduled jobs, reminders, quotes awaiting approval and overdue invoices, with a 7-day weather forecast for planning.
Jobs & calendar
Jobs move from quoted to scheduled to completed, and a month calendar shows every booking with the day’s revenue.
Quotes & invoices
Create quotes and invoices, send them, and see each one’s status at a glance — including Scope of Work on quotes.
Document preview
Branded quote and invoice documents can be previewed and zoomed before they go to the client.
Profit tracker
Income, expenses and profit for any period, with a performance chart and a breakdown of where the money goes.
Expenses & receipts
Business expenses are tracked in the app, with receipts and files uploaded alongside them.
Inside the app
Every screen, one place.
The app’s store screens, from the Google Play listing. Android · iOS coming soon.

Responsive
Same story, every screen.
The landing page keeps its dark, hot-pink look from a wide desktop down to a phone — where the app itself is meant to be used.


Look & feel
Night black, hot pink.
Colours sampled from the live site.
Heavy, tightly set sans-serif headlines with a hot-pink second line, paired with condensed capitals in the app’s store screens.

Client feedback
In the client’s own words.

HMA
Cerrow took a long list of features and shaped it into an app that feels simple. Their design decisions were always explained, deadlines were met, and the launch on Google Play went without a hitch.
