For the farmer/stock breeder this app displays the estimated due date for the birth of the young of various animals based on a normal gestation period.
When an animal species is selected the screen immediately shows the gestation period and the due date based on the current date.
A Birth Record can be created based on the data from the Calculator and updated later to record actual number of offspring. These records are available easily from the main screen.
Note that gestation periods are estimates and will vary somewhat for individual animals.
Optimized for iPhone 5.
