The bugs that I brought up in my original review have been corrected. There still does not appear to be any onboarding guidance or real-world training on its use. So currently, any knowledge I have on how to use the app is from my own experimentation and working off of assumptions. Still need to experiment with the "meeting" portion of the app to test the voice recognition/note taking portion.

Unlike some other apps I've tested, the QR code does give the option for a vcard download and import, so the other conference attendees don't need to be using the Conferly app to have that work.

(original review)
Since purchasing and activating this app, there has been zero onboarding guidance or training on the usage of the app. If you look past the bugs or incomplete processes, there seems to be a good core of an idea to build on. Apparently, in it's current version (0.11.0) if you didn't authorize all permissions at install and launch, the app doesn't work. Cannot update profile picture, record a meeting, or display your QR code. And their only fix? Uninstall and reinstall. Tried and it didn't fix things. I don't have a conference to attend for a couple of months, so hopefully they will get it all sorted out by then.
