The main inconvenience of SkyBet is that the app is no more than a shortcut to SkyBet's official website. That's the only thing it does. This basically means you can do the same thing from your Android as you would from any desktop browser.
As usual for sports betting apps, SkyBet users can bet on final scores or on other specific events. For example, you can bet on who will score the first goal of the game ... or who will win.
SkyBet is a decent app because the mobile version of the website is decent. That said, the number of different sports events you can bet on is outstanding.
