Work carried out
ListIt was created to solve the chaos of shared shopping lists: duplicate entries, outdated lists, difficulty splitting expenses and no real-time updates between group members.
To create a single source of truth for lists and expenses, accessible on mobile, with instant updates, secure authentication and notifications about changes.
Name the list and start adding products with name, quantity and category.
Invite family or friends by username or email: everyone sees and edits the list in real time.
Tick products off as you pick them up: the status updates instantly for everyone.
