Four Apps to Make Grocery Shopping Easier in Billings Enter your number to get our free mobile app I have a friend named Jax that created a running grocery list that he kept on his cell phone – way back in 2006. He had listed out his favorite items, sorted by department, on his iPhone Notes. Jax would put a checkmark next to the items he needed; if he was shaving and needed new razor blades, he’d pull up his phone, scroll to the HABA (health and beauty aids section – I wish I was joking), and check razor blades off the list. It seemed like a little work on the front end for maximum efficiency while at the store shopping.
