Incredible event app

Best event management app out there. We use this at our company and it’s great for managing mid sized Corp and customer events. I also use it to manage personal events. The new ticket sale feature is a game changer. Super easy to use and collect payment. Their new releases keep adding value and faster performance. Highly recommend this app over the others!!

I love the idea of Diobox, except for the payment. $22 a month could go towards other things, like better quality meals. I like good quality things, but I have a budget. I think it would be better to lower the prices-but I am an entrepreneur, so I am still figuring out how much should be spent on certain things.

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.
