SNACK & NOW are a pair of plastic rings whose mission is to help diabetics to remember whether or not they have injected their insulin dose. People with type 1 diabetes need multiple daily insulin doses. Over time, when injecting many times a month, this action is done mechanically and becomes a routine, and so sometimes it is hard to remember if you got your dose or not. On the other hand, distractions of the daily life can make you lose concentration in that important moment. SNACK & NOW reminders allow you to put a mark on your insulin pen that helps you to clear that doubt. SNACK is designed for using with rapid-acting insulin pens and has 4 icons that correspond to Breakfast, Lunch, Snack and Dinner. NOW is designed for being used with long-acting insulin pens and has 7 icons, one for each day of the week.
