Happy to see this
Of course this app has been developed with Xojo, which sounds good.
But, after installing on 2 android phones I see that there is sometimes more text than fits on the screen as a whole, while you cannot scroll. Scrolling is trivial for reading it all, so there is a little bit of work to do on this app to make it really a good first impression.
Guess at the conference there will be given more information about mobile developments and how much code was needed to create this application.
I can only see “Favo” in portrait mode instead of “Favorite”. I click Favorite for several and after closing and opening again there are no favorite sessions. How should Favorite work? (This on Android device)
What text doesn’t fit? On what screen?
Yes, Travis and I will be talking about Android at the conference and I’ll be showing the Xojo code for this app, among many other things.
Yeah, looks like I didn’t get the locking set up correctly for the Favorite switch or the presenter image.
I see what is happening here. When the app is quit by Android some data is getting reset that should not be.
Looks like I have a couple things to fix. This will give me a good opportunity to test submitting an app update to Google Play 
and is why we put this out there ahead of the conference.
Looks good, I found a couple of things <https://xojo.com/issue/59279> <https://xojo.com/issue/59280> and one from Tim <https://xojo.com/issue/59278> (in case you didn’t notice we’re adding to feedback)
