List Engine App
List Engine is a simple to use, yet powerful app that allows you to manage ALL of your lists in a simple and intuitive way. At any point you can group your items by store, list, or custom tag — that way when you’re shopping at the store you can simply view ALL items from every list that you need to get from that store.
Because List Engine automatically saves each item you never have to re-add it to your new lists in the future. You can simply create a list from previously created items.
If you have a recurring list you use frequently (like a grocery list), you can clone clone it to start quickly and then modify it as needed.
Create custom tags so you can group your items by more than just stores and lists — you create how you want to group your items.
