Working on a wedding Layout App

This is an app a couple of us have been working on for a minute. Its called preParti. Currently its in beta but we have a working version of it on Google Play. Any feedback would be great! Ive been working on this with my sister and everything on this app is too scale. You can place your tables and chairs down and even send the file to a friend. Hopefully this thing will take off. We are pretty proud of it.
