I have been using this app for 6 months at various tracks and had very good luck with it.
On my worst day I broke even. When I use the graphs I am able to see the race at a glance. Because of my bad eye sight I can’t read the form very well and this puts me right back in the game. When I needed some ifo on the program they responded quickly like I mattered. They listen to suggestions and use them if they can. Can’t wait until the next update. Thanks
