It allows users to view herd data, manage worklists, and enter transactions from a handheld Android device. This guide covers the installation and setup steps to connect the app to DairyComp. Installation is the first step; the device must then refresh from DairyComp to function. ## Before You Begin | ******Topic****** | ******What to Know****** | ******Why it Matters****** | | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------- | | Recommended Device Types | Install Pocket CowCard on an Android mobile device.
