YiFFr

YiFFr was a mobile instant messaging app for Android Versions 1.6 and higher, used to find, meet and chat with local furry friends, singles, and find yiff.

History
YiFFr was discontinued indefinitely by its creator, after Google pulled it from availability in Google Play citing it to be displaying porn, and not screened by staff.

The author had planned to re-release a new version, but has not been heard from since making this statement, and the YiFFr website has been put up for sale.
