The whole evite platform works for me, I had my birthday this past weekend and it was easy to track guests, to get an accurate head count for catering and to reach out to individuals or groups was simple. The mobile version helped me keep track of things throughout the day and not just at the end of the day when Im home and just wanna veg out. At the party itself the photobooth made for an excellent featured activity - we had a lot of fun going through everyones the next day. Love it would use it again, 5 stars.
