How to sync surveys made in KoBo website with KoBo Collect App?

Hi there, I just signed up to and created a test survey there. Then I downloaded the KoBo Collect App hoping that I would sign in there and be able to see and fill up surveys made through the website. Is this possible? if not, how could I achieve a similar result? In the end, what I need is to design a survey that 3 guys with tablets can easily fill out while asking people in the street and have the results consolidated in one organized DB to process later. I will greatly appreciate any help given on this matter!
