X-Out for iOS:
If you’re looking to X- Out a home on your iOS device simply view the listing and click on the ‘X’ icon on the property page.
If you’re using the map view, homes you X’d-out will appear light green.
If you’re viewing homes from the list view, you will see an ‘X’ next to the green home icon.
If you’d like to remove a home from your ‘Favorites and Comments’ section, just double-click on the heart icon shown in the upper right-hand corner of the photo.
From there, that home will be removed from your list.
At this time, the iOS does not have a section for you to view all of your X-Out’s. However, you can view these directly from the site.
