Web entry for household grocery lists.
I'm the only one in the household with a cell phone. I'm also the one that does most of the grocery shopping. I'd be THRILLED if my roommate could create grocery lists via a web interface for a store that I would be able to pull up on my phone.
Someone told me of another app that is a combined calendar/grocery list that does have this feature, but I really like Marche and Awesome Calendar so I don't want to get a new app.
