Tap your picture at the top left to open Profile & Settings, tap Settings → Keeping Count, and turn on Keep Count of What I Have. (Quick Setup can turn it on too.) Then each pantry item can be counted its own way:
- Automatic — what you have goes up when you buy the item and down when you make a recipe or have a planned meal that uses it. When it runs low, counting what your planned meals will need, it goes on your list by itself.
- I'll Update It — you update the amount yourself. Menu Planner 2 won’t change it or add it to your list.
- Have It or Not — you just mark whether you have it or not, and buying it marks it as in your pantry. Menu Planner 2 won’t count how much you have or add it to your list by itself.
- Don’t Keep Count — not tracked.
New items start with the way chosen under For New Pantry Items on the same screen. To change one item, open it, tap the pencil button (Edit), then Keeping Count → How to Keep Count. Or open the item and tap Keep Count (Change Amounts once it’s counted).
