Best Before is a simple app that helps you keep track of anything that may expire, like food, or your passport.
It allows you set two notifications for each item on the date it expires and on the date that you want to be notified so you can deal with it in advance.
In order to fit into your workflow, Best Before allows you forward an item to another app under the rules you set in settings, from the detail view of the item, or from notification actions directly.
Items are classified into two types: Renewable and Restockable. For renewable items, only the last item (with an identical name) added will be kept in the list. For restockable items, items will stay in the list until you manually remove them.
Hope it helps.
