It's a great app that offers everything you need in AC. A display for DRS, ERS etc. would be good. I was most surprised by the sector display. It makes it much easier to assess where you drove better or worse. In fact, I currently only use the leaderboard and the sector display. I noticed that on the leaderboard, if someone starts from position 1 and has made a false start, they are still shown in position 1 during the race, so that the actual position is no longer displayed correctly. Nevertheless, the app is worth its stars.
