Sitewise: a construction crew app and web admin, concept and clickable MVP prototype

The company needed all job site work in one place: who does what, what status each task is in, what the photos show and how many hours were worked. Management needed a view across all sites without calling crew leads.

The worker app had to be simple: large controls, minimal text, usable with gloves and on the move. The admin, by contrast, is data-dense: lists, filters, a kanban board and timesheets.

We defined the roles — worker, crew lead, supervisor, office — and built a set of flows for each. The mobile part is large and high-contrast, the web part is dense with tables and cards, and both share one design system with a common palette and statuses.

The prototype opens via a link in the browser. For the MVP we recommend Flutter for the mobile app, React for the web admin and a Laravel backend with PostgreSQL; photos are kept in object storage, and timesheets are exported to the accounting or ERP system.

The product's value shows up where roles meet: a worker marks a task done and attaches a photo, and the supervisor sees it in the admin right away. That is why we built both parts into one prototype, connected by shared data — the same job sites, tasks and people.

This lets the client check the whole process end to end, from a task on site to a timesheet in payroll, and agree on the MVP scope before development.
