Yes, I'm finding that a problem with the RC Timing app - and I guess it will be an issue with other apps that work on colour recognition. However, LapTracker works differently, focusing on a 'lane' - more like the Carrera and Ninco bridges - and has excellent fine-tuning features. After I mastered the set-up, I haven't noticed any miscounts over hundreds - or probably thousands - of laps of single car running. Two-lane counting with LapTracker requires careful placement of the device - preferably above the track.
