Dinner Planner allows people to plan out their daily meals in an organized and efficient manner, share recipes with friends and even organize your grocery list (automatically). We send out daily reminders to people on what they're cooking for the night.
Tonnes of features are planned including SMS notifications, subscriptions to weekly menus, generate meal ideas based off what ingredients you currently have.
I realize there are other apps out there like this one, but to be totally honest, there aren't many good ones.
