This is meant just for computers, right? A quick check of the readme showed that devices must run this or that commands, which seems difficult to do on an smartphone. I guess the ngrok-like setup would be the way to go for that case, given the increasing prevalence of phones and tablets as the single form of computing for lots of people
I've been thinking a lot about this case specifically. And you are right, phones are largely not supported right now - I've been researching how to make that happen. One case I've found that works for me currently is running connet via Termux - and I've made the necessary changes to support that.
Native iOS/Android clients, if possible, will probably be the next things I'll work on. At minimum they should enable you to run a "source" (e.g. a consumer of an exposed service), but ideally it will be the whole deal.
