Simple and Reliable App For Event Check In (800+ registrants)

I used this app to help speed check in for guests for an event with more than 800 registrants earlier this year. It was surprisingly simple to set up and it worked great even with 3 people simultaneously checking in our guests (one via ipad and myself and another colleague using our iphones).

I had a few questions during the initial set up and support was very responsive and helpful. I appreciated that they also accommodated for a one time payment to test things out for my event.

I recommend this app if you need a quick and simple way to check in your guests even for larger scale events with 1,000 guests.

Best Check In App!!! Highly recommend!

We hosted a charity event with over 800 people. We had multiple check in locations. This app worked flawlessly and was super simple to use. The check in time for each guest was cut down to seconds. The real time as well as the after event analytics were incredible. It gave information we were never able to obtain in the past. The customer service was also top notch. They went above and beyond every step of the way. We plan to use this app for all events moving forward. Whether your need is large or small, I highly recommend this app to anyone having check in needs.

OneTap made our complex event check-in much more efficient and reliable. During and after our event, OneTap provided our organization with data analytics to assess customer behavior, confirming attendance with real-time, detailed information. EVERY event should use this platform for tracking invitation lists and attendance!

THANK YOU for bringing easily accessible, affordable, customizable technology to the cumbersome Check-In process!
