Thanks a lot! Bookmarking and downloading your reply. I'll most certainly use the following months to try and find the perfect balance between usable and secure app.

Sadly, on the topic of the Turing Phone, I suspected as much. I really like to believe but yes, they're quite new to the market and are still closed in terms of what they use for this alleged "more secure" phone/OS. I'm still interested but my enthusiasm is not so high compared to the time of the original announcement...

I wanted to use Signal several times but I have to admit, it's use-case and convenience points aren't looking well. I'll take a more serious look, though.
