Going back to the previous screen, Ginny presses the "Select" button for Washer 3 and Washer 5.  This changes the color of the button, as well as changes the text of the button to read "Deselect".  If Ginny presses the button again, the button will return to its original state.  Ginny can also hit the "Back" button to return to the homescreenhomepage, or "Continue" to proceed.  Ginny presses "Continue".

Here, Ginny can see the washers she selected from the previous screen.  The "Back" and "Continue" buttons remain at the bottom of the screen for consistency.  Each washer image has a "Leave Note" button, which Ginny can press to leave a message for the person who moves her laundry to the dryer.  Ginny does this for Washer 3.
Again, a popover appears, where Ginny can type types in her message and press presses "Leave Note" to finish the action. This closes the popover, and she presses the "Continue" button once more. Image Added
Ginny now reaches the end of the workflow.  This screen intentionally looks very similar to the homepage, so that Ginny gets the feel that this is an entry/exit point to the app.  Ginny sees how much time is left until her clothes will be done, and can press the "Notify Me" button to receive a text notification when her clothes are ready.  She chooses to do this.

This is the version of the homepage that Ginny will see until her clothes are finished washing.  It's nearly identical to the previous screen. Image Added
This is another version of the homepage that Ginny would have seen at the beginning of the workflow if there were no open washers or dryers.
