The news originally came from the podcast "From Eorzea With Love"(in Japanese) where Yoshida-P was interviewed. The above link summarizes the news and translates as follow:

New FFXIV App in the making

Will allow to chat with FC members(among others)

Planned to be released around Heavensward.

Sounds good It was a very small announcement near the end of the podcast, so no details revealed yet.
