where is the open house planner in the ios app

Not in the app unfortunately, but you can access from http://streeteasy.com/open_house_planner?site=nyc

From a browser, on the menu, "RESOURCES" then "Open House Planner" or

I don't think the app supports it because when you try to add an open house from the app it sends it to your calendar.

Thanks for all the help!

pw036, so how do you add an open house to your IPhone calendar? Any reason to mind this?

ximon, personally I prefer to search on my laptop, using filters and browsing is much easier than on the app, plus I can open multiple tabs with one property in each. I add the open houses to the planner and then print a list and work out a route and schedule on Sunday morning.
The app has an "+ADD" button if you want to add to your calendar, but having multiple "Open house from StreetEasy" events all around the same time, isn't really that practical if you have more than one open house you want to attend.
