Lost saved properties in rightmove app after doing restore. Can i get them back?

Hi I have had to backup my iphone as it is getting serviced at the genius bar. I hjave been given a spare phone which I have retored to the backup I made yesterday. The problem is I have 100+ saved properties in the rightmove app. When the backup is complete and I open the app they are all gone. This is 6 months of research that I cannot get back as the majority have now been taken off the market and are unsearchable. PLEASE help!!!
