if suffers from the fact that libsodium (their encryption library) is inherently weaker than something that implemebts the Double Ratchet encryption algorithm. The most notable deficiency is that it doesn't to Perfect Forward Secrecy, meaning if *one* of a chat's keys leak, your entire chat history leaks, not just one message.

These are important things that they've failed to address. 

 What is yall’s opinion of SimpleX ? 

 I use it and I like it.

Uses double-ratchet from Signal + some neat quantum resistance stuff, uses user-selected relays to send messages and doesn't use persistent user identifiers. Lots of metadata privacy to be had :) 

 Is it good for day-to-day use like to talk to my family, for example?  

 I would say yes, just make sure you select the kind of notifications you want 

 generally yeah, unless you're looking for some more fun social features (stickers for instance)
