Tapatalk is the app to access FI on your phone.
Hmm it wouldn't let me in that way before I'll have to check into it more. Rarely use a laptop anymore so mobile is when I do so that results in a lag in checking in at times. Honestly I like what I see with fantrax but once again it could hinder the consistency in my checking in.
There's a Fantrax app for the league and there's a Tapatalk app for this site.
