Ratings and Reviews

Guest CRM and check-in app combined


Really happy that I found this app. It has a much nicer interface than zkipster and the other check in apps, but it offers so much more functionality.

There is also a CRM feature that lets you see total RSVPs, no-shows, and guest history from previous events.


Best app for quick guest registration


I was able to sign up and import my guest list directly from my iPhone contacts. Didn't even have to login to the website. Very easy to use and quick to learn. Highly recommended for events and parties.

Easiest check in app I ever tried


This is by far better than other check in apps I tried and it includes so many features. Clean interface and fast. Works nicely on both iPhone and iPad. It's a must have for anyone doing mass guest check ins.
