The Cow Master app is a dairy management app for farmers to keep track of all the activities in their farm. It will record all the details of the farm from the cow's arrival to their departure, along with all the events that happened during their stay. 

The Cow Master app will keep track of the farm's activities, including milking, feeding, and any other activities that may occur. It will also track the progress of the farmer's tasks, such as how many cows they have, how many liters of milk they produce each day, etc. 

It will help the farmers to manage their dairy farms.
