Betting apps

[oobster]

Chaps,

I've been a long-time fan of F1, I haven't missed a race in over 10 years and in order to spice-up my viewing pleasure slightly I would like to perhaps put a small bet on every race during the 2015 season.

I am fairly new to betting, so any pointers on decent user-friendly apps, preferably iPhone apps, would be appreciated.

Ta!
