Android App

hi,

I wonder if anyone know if there is any app for Android-device, to follow profit/loss at betfair?

None that I know of but you can actually use Teamviewer(yes this is free) so that you can remote to your home computer.

I am just interested to follow my profit/loss and I was hoping there was a simple app showing a trend of my profit, in my cell phone.

Hi
This is Betfair's mobile app for Android. You can check your balance when you log in.

Some other ideas:
How about setting up a trigger to email your balances or any other info you want at intervals during the day, and pick up the emails on your phone. There is also the subscription SMS service you can look at.
