Switching Dates in the App
Generally, you'll enter data into the app on the day that it occurred. However, if you'd like to enter data for a date that has already passed, you do have the ability to input on a date in the past.
From the input screen, click the blue calendar button in the top right hand corner to bring up the 'week view.'
From the 'week view,' select the week you would like to enter data for.
