    Couldn't be happier with this app. Very accurate, announces your time each lap, videos the laps, and auto sync to Facebook and Twitter. What more could you ask for ?? One happy little vegimite !! ☺

    Hi the app works fine .I have found the gps positioning is not good enough to get any usable data from it . Constantly showing between 2-5 metres out even with external 10 hz reciever also position floats around .It will show you driving all over a straight road. Its not the apps fault .

    It has worked great for me so far. I've been using this app for about a year now with no problems.
