Patience is a virtue
Hard to rate the app as it appears there arent really any mobile surveys available. The complaints about a blank screen is probably due to the fact there are no surveys, not that the app is faulty. I could be wrong...
Update: Yeah, had this app for 6 months and have had two mobile surveys available and one wouldnt even open. Pretty much worthless at this point.
