expiration reminders
  • informed by current items in the user's inventory
  • occur on a set schedule by the user as to not overwhelm them with notifications
financial waste
  • based off of how the food in the user's inventory is used, financial waste is tracked and visually updated each month
  • motivates user by promoting financial savings
