1.Automatic Pop-up
When your session ends (whether it times out or you turn it off manually), the App will automatically show a pop-up window where you can record and save your milk volume.
2.Manual Entry
You can also add a new pumping record manually from the "Statistics" page or by tapping the small bottle icon in the top right of the pump control screen.
