So I rely a lot on Signal these days, but I have been looking for a second backup method in case signal has an outage or is taken down by the Fash. The only thing ive found that looks good is @simplex in fact it looks great from my perspective but because its a little less friendly I think I won't try to change my non nerd friends. i will use it for a secondary comms when signal is down with close family probably. might switch close family to it as primary even. giving it a try.
