iPhone tuning apps?

I have only found one but it has no reviews and I don't know if it's worth the $4.99

There's GTune5 but that is more of a tune adapter than a tune creator. More info here https://www.gtplanet.net/forum/thre...-ios-now-supports-all-cars-latest-dlc.260700/ and here http://www.gtune5.com/
