Buy me a pie is one super cool app. If something is missing in the fridge, and I have no time, I can smartly create a shopping list to then share with my family. So they know directly what is needed and can purchase already done. So far I have not missed in the list and could indicate anything directly. Clear would also the classic version with pen and paper .... but in this day and age this gimmick is already standard. And that is why five stars from me! :-)
