You can create shopping list(s) for yourself, your family, friends, housemates, events and collaborate in real time. No one has to sign up or install anything on their phone. Just tap on your name and mark the items as purchased as you walk through the shop isles. You will have inventory and purchase history to help you organize your shopping a bit better too. Check out the 39 seconds short video I have prepared showing one person on their mobile phone at the shops and one other person on the right at home, working on the same list real time.
Hoping this tool will prevent endless text chains between partners/families ๐ You can always see what you need to get and who can get what when you throw a bbq ๐
