Whoever downvoted, a comment explaining why would be nice, when the cell tower generators are out, and there is only phone battery left, offline communication options could be useful, I'm glad I'm not in that position right now.
When I Googled it, the apps listed include Firechat, Signal and Briar. Signal is centralised, Firechat is dead, and I don't think Briar are current either? I wish it was a simple web search. Even Deep Research needed the ML pot to be mixed around a few times until it gave an good answer.
Seems like some people are not interested in honest and useful feedback because this got downvoted too! I thought it made clear points about an important topic. Well, whoever sees fit to do this, I hope you get whatever it is you want.
