Up front I'll be honest and say that I'm a better than average driver but a horrible tuner. So I depend on tuners and their hard work but I have problems when I can't find a tune for a particular car.
Enter Gtune5.
The app is well thought out and well made. It's easy to see a lot of time has been put into it. However it's not particularly useful other than to store your current tunes and or detune a car so that it can compete in a lower pp race. I don't need that and I'm sure most drivers don't either. I'm in need of a gadget that provides suggestions or calculations for a tune like the FREE spreadsheet for tuning GT5 cars that can be found here at GTPlanet.
I'm not completely unimpressed nor do I want my money back but I also can't recommend this app to anybody either.
