This app let's you store information by creating virtual "cards". You can think about this like the old-fashioned rolo-dex systems, but (hopefully) more practical!
Each card contains a specific set of fields determined by the card type. You can create multiple card types for each type of information you want to store. For example: a project card, contact card, etc.
The cards (of different types) are added into a collection. You can think of a collection as a file cabinet. The collection can be searched as a whole. Collections can also be shared in a team, all members have access to all cards in a collection.
Cards in a collection can be linked to each other. For example: link task cards to a project to keep track of things to do for a specific project.
