The description doesn’t say anywhere that I could find, but the free version is limited to 10 sign-ups! Speaking from experience, if you bring it to a trade show and hit the limit, it can be very annoying.If the description was clear about this, it would be a lot better.

The app is fine, in spite of some irritating bugs (freezes, unresponsiveness, et al). The reason for the single star is because it’s unusable if you’re not on WiFi. When you have i5 at a trade show and a potential customer enters their info, it won’t the data if you’re not on WiFi. We lost a bunch of potential sales due to lost data, and that’s not even counting the frustration that comes from paying for something as bad as this app is. It really needs to not be an option for download with the number of glitches it’s riddled with.

The product worked great and functional but you cannot email the guest list to yourself. I tried multiple times. The developers contact link for issues does not work. I lost $4.99 and valuable time. Don’t waste your time.

I didn't see the in app purchase of $4.99 for unlimited entries. But I discovered it when the 11th person couldn't submit their email. This happened at my event with no wifi connection; so I couldn't have upgraded even if I wanted to. Honestly, I was pretty pleased with the functioning of the app, love the ability to customize the lists and collect emails offline. It's probably worth the $5 but now my event is over and I'm too annoyed about it not being more clearly stated that I only get 10 entries that I may not get it.
