EventMobi has helped our organisation to conduct virtual conferences during the pandemic. It has also helped us to include all the information and reduce our costs on printing and boarding. Instant updates and messages can be sent. Also, regular updates and better customer service have really helped us to do the business in an easy way. You get some insights on Event Technology, Session Feedback, Survey, Email Marketing, Attendee Networking people. Where this has lacked - If we were being given an option to add in our own custom fields within the agenda/session descriptions.
Most of our meetings are too small to bother using it but it is great for our larger workshops. If you have a complex schedule or agenda it is better than a paper agenda and allows you to adjust changes live in the agenda during the meetings. We only use it a few times a year because we only have a few larger meetings.
We really do not have any other experience with other apps. We like that Eventmobi is easy to use for both us and our clients. We can add attendee names with their picture and contact information manually or import them. We can add speakers, agenda, pdf hand-outs, hotel information, etc., easily.
We use both but for completely different reasons. We use Guidebook to manage our attendees and communicate with them during large workshops. We use Airtable as a spreadsheet type database for tracking things.
