I don't get this app. It's basically a wrapper around FREE Jitsi Meet. You can have same if not better result with several hours of work by only using a jitsi meet server (self hosted or not), wordpress, buddymeet or any other jitsi wrapper and few other customization you might want. The advantage of using WP solution is that you can add as many features as you want and just generate a wrapper around your site dynamically updated. And there you have a better app, with more options for only hosting costs.
All apps that appeared due to pandemic and are relying on free videconferencing servers are, in my humble opinion, just a reap to your pockets.
Even Zoom it's a jitsi server rebranded and a bit reworked. Another promoted app Cisco Webex uses the same jitsi technology rebranded.
