How was your actual UX with Briar? I tried to get family to use Briar during a flight and it was pretty poor. Messages wouldn't show up and we were worried about disconnecting from personal Bluetooth headphones while keeping using Briar. It worked okay and at one point my partner and I chatted about landing plans when the person next to us was asleep. But we found that just passing the phone around with typing worked just as well. It worked okay for the other family but again, was a pain.
