As an event app expert and event planner, these are 2 apps that literally helps me so much:
Socio Event App
This is a networking and guide app for events. So you can organize your event by putting your agenda, announcements, sponsors & exhibitors, attendee list, and literally anything else...
It also lets your attendees literally shake their phone to discover, network, and exchange info with fellow attendees. Not to mention there's a chatroom system, social media wall.
I like this app because it lets me cut my printing cost completely from the budget and makes my job 1000X easier, my attendees love the fun, and my sponsors love the traffic it brings to them. Socio is new and looks nice. Overall, I think it's a must-have!
This is a graphic designing app that lets event planners make amazing looking designs to post on social media. You can design from scratch, or just use their models, or both. After you're done, it lets you download it in JPG, PNG, and PDF file types.
I use Canva for all my social media posts that need a graphic picture. Really nice and easy to use.
Here's the link to Canva.
Really hope this helps! Let me know what you think
