Sync21 is a data storage and reminder center for breeding programs on dairy farms. Its main objective is helping the user get more cows pregnant. The user is able to enter cows into the system under three different actions; Pg injected, Ovsync& bred. The app sends notifications to the user for each individual cow depending on which action the cow was entered in. For a cow entered as PG Injected the user will receive a notification 2 days later asking if the cow is in heat. User can then choose Yes or No to as was the cow in the heat, if she was, the app then ask user if the cow will be bred. If yes she is then automatically added to the preg check list. The app automatically compiles a list of all bred animals with how many days ago they were bred. This makes preg checks with the vet very quick and simple. If a cow was entered as bred the app notifies user 21 days later to check for heat, and from there follows through with was she in heat, being rebred, no heat, etc. The user is able to enter their own personal ovsync schedule; user will receive notifications for ovsync animals based on this schedule.
