Lappen

Lappen is a shared shopping list for the household. Make a list, invite the people you shop with, and check things off together. Changes appear on every phone within a second, so no one needs to refresh and no one buys the same thing twice. Items can carry a color, lists can be starred and reordered, and widgets put a list on the Lock Screen or Home Screen.

Highlights

  • Shared lists. Make a list and invite the people you shop with. Everyone can add, check, rename and remove items.
  • In sync, live. Changes appear on every phone within a second. No refreshing, no double purchases.
  • Invite with a code. Share a link or read out a six-character code. Each code works once, for seven days.
  • Notifications. Get a notice when someone adds items to a list. Each member can turn off their own.
  • Widgets. Put a list on the Lock Screen or Home Screen. The Add item widget opens the list with the keyboard ready.
