The app includes all the tracks and cars from ACC, with more than 1000 fuel usage values and 100 lap times, so all you have to do is select the track, car and duration and the app will give you all the informations for a successful race, with safe, balanced and fuel saving strategies.
It also handles additional rules like pit window, mandatory pit stops, maximum driver stint and refuelling rules.
Pit stops are editable, so you can move each of them earlier or later into the race as well as choose if you want to change the tires or not.
Once you're happy with your strategy, you can save it to open or edit it later, duplicate it, rename it or share it with your friends and teammates.
