CartPatt

I made CartPatt because my family kept buying the same things twice. One of us would pick up milk, and someone else would grab more on the way home.

Everyone in the house adds to one list and checks things off as they shop, and it syncs to every phone. When you add something the family bought recently, it tells you first, like "Already bought 2 days ago". Finished trips are saved to a calendar, so you can look back at what you bought and when.
