Unfortunately, the app doesn't work. I downloaded it and when I visited properties I tried to check in. The app either found no properties or properties other than the active listing I was standing in. The app is good at finding out of date listings and on very rare occasions, an actual active listing that I visited.
I provided feedback on the app a number of times, asking what Truliia planned to do to either fix the check-in feature or discontinue it. The answer was....well, nothing. They never bothered to respond. Super disappointing!
