If I used a smartphone everytime I placed a bet I would like a gambling addict. lol . I place over 300+ bets a week.

Its probably something that a lot of people could get use out of though. Most bookies have the smartphone apps so I assume there are a few out there for racing but never looked.

I write my programs to run without my help so they just run without me needing to be at the computer so have never really had a use to write a smartphone app for racing. The only one I use is betfairs so I can check how much my account balance has gone up today
