There are four categories you can place your animals in on the Moocall Breedmanager app; in calf, cycling, in heat and inseminated.
To place an animal in one of your smart lists, create the cow's profile, find the cow using search (top left corner), and then scroll to the bottom of the cow's profile.
Here you'll find the events menu. At this point you're given options like Add Calving, Add Heat, Add Insemination or Assume in Calf. This adds them to any of the categories.
From here, the app reminds you of important dates, for example when calving is due, when the next repeat heat is due, when the next cycle is due and any previous heats.
