Some WIRE questions

I recently been told it'll be more convenient to use Wire rather Signal, I like Signal but honestly its UX isn't the most pleasant, It doesn't alert me when I get a msg(I uninstalling and installing and it works for a time) but ok maybe its something wrong with my phone, sending pics etc between friends, any way

So the developers of wire are the same who was behind skype, which isn't the most secure, also im not sure how they are handling metadata, which is somewhat important for me,

Any thoughts? I know there is threema which considered to be good
