I switched to Diverse Solutions products from IDX broker in 2013 and am not sorry. Their mobile IDX app is excellent. I have no complaints and would recommend it with no problems or issues.
Our local MLS mobile app is horrible so I send all clients here to search for properties rather than our public facing MLS site.
I also use Diverse Solutions on my own webpage for regular search and think it is graphically superior and more practical than others I have tried in the past.
