There are programs being sold online that act like calendars, prompters and organizers. They remind people of key dates and events, on top of systematizing and storing data. Collectively called as hobby software, they span wide-ranging categories like health, travel, sports, cars, aviation and food.

If you want to catalog and classify your recipes for example, you can search for relevant software in the food section. One existing program for recipes can accelerate the search process, adjust serving sizes automatically, showing video clips of food preparation techniques, and display photos, print menus and nutritional values, among many other features.
