I use this app https://play.google.com/store/apps/details?id=au.com.realestate.app I'm sure there's an iPhone version if that's what you're running. I've had lots of success looking for places here and setting appointments for viewing times. Sometimes if there's no viewing times advertised in the app it pays to actually look at it on a computer cos they're on there. It's not perfect, but it's a lot better than it's been in the past.
realestate.com.au is better. They have an app too.
