Yes click more tab, online and then select and it will show you active tracks and you can watch people in real time.
 
where do you mount your phone when lap timing? does it need to be on the dash or back window to get a good signal for the gps?

most trackdays dont allow sucktion mounts they have to be bolted to the car etc. and im not a massive fan of drilling holes in my dashboard. can you recommend any sneaky tips? strapping to the sun visor?
 
Just been checking out Harry's lap timer. On the apple App Store there are 3 different versions. But it isn't clear what the difference is for the money. Anyone shed any light?
 
It's all you need tbh but you can upgrade via the app if you want.
