The Buy The Way home screen with a shared shopping list

The problem

People who shop as a couple or with flatmates usually rely on a note on the fridge or a chat full of "did you get the milk?". I wanted a shared list you can use with one hand, in the aisle, with poor signal.

What I did

  • I built a PWA you install on your phone, without going through the app stores.
  • Changes reach everyone else in under a second and the list stays usable without a connection.
  • Sign-in with Google or with an email link, no passwords.
  • Products grouped into 15 aisles, in the order you meet them in the supermarket.
  • Automatic releases, with a dedicated pipeline to roll back if something goes wrong.
  • Unit, end-to-end and accessibility tests that run on every change.

The result

The app is in production and I use it every week.
