Phone LG G Watch/ android wear Apps and updates

I use Hangouts for messaging, are there any other sms apps ppl like using that we could use our original phone number on the G watch that we can reply with?

I don't really like hangouts and how they don't show anything but Google contact photos. Just curious of to what everyone's setup is like. I'm really liking the G watch and the convenience of it, no question android wear has a long way to go.

Which apps do you find convenient and worth the download besides watch faces?
