Great app! I had issues with racebox not connecting. But learned that you need to disconnect the other apps. Works great!!

My viewpoint is coming from some who is a cone dodger, not a track person, but I think if anything the app will work better for track usage. My 3 suggestions to go from a 4 start to 5 star app would be: 1) let me install the iPad version on my Mac so that I can review data on my much larger external monitor. 2) allow me to play back the run in slow motion (1/2 speed, or 1/4 speed for example). Inputs in AutoX are so fast that I’m always trying to pan through the run in slow motion to digest the elements and what the car is doing. Can’t do it in real time. 3) this may not be an iPad problem but at least on my phone the map by default is too zoomed out. I know autoX courses are smaller than tracks but the map by default is too far zoomed out on my phone to even see where in the run I’m looking at. I always need to zoom all the way in before I can look at any data, otherwise I have no context for where in the run I am.
