Professional UI design for existing household management app

Professional UI design scheme needed for existing household management app built with Flutter. The app supports responsive design across desktop and mobile screens as well as light and dark modes. Currently there are four main pages - Home, Items, Users and Settings - with associated sub-pages.

A polished, consistent design is required to enhance the user experience on Web, Android, and iOS. Designs should cover interfaces scaling from half desktop to phone size, address light and dark themes and provide consistent font and colour themes. Overall design themes/schemas will inform how pages look. Major pages (about 10) will have individual designs. Unique elements like date pickers will have mini designs.

The goal is a delightful, efficient design system supporting the existing functionality across form factors. Freelance UI designers are invited to submit bids with portfolio examples.

The successful applicant will be given more details on the app. You will be provided with a unique sign-up code to see and interact with the existing implementation. Additionally you will be given screenshots from an active family to see what real data looks like.

We will need to negotiate on the output work artefacts which will need to be viewable without any further licences. The artefacts should depict and describe what the app will look like and how it will interact with the user. The artefacts will directly inform developer re-implementation of the UI for the app.
