It has a couple of really good use cases as it works on non-phones (macs and ipads). Little kids and some older people don’t have phones. I like the bigger screen for non-casual video calls.

Also, I was on a project with a colleague who had a poor internet connection and we found FT worked better than zoom. FT video quality seems to be the best of the services I’ve used but personally I don’t care about this part much.

I wouldn’t call these “killer features” but they are enough, with the integration into address book etc, to make it flourish.
