Apps IMO are fine if you are not wanting accurate reliable information track to track. By using the same gauge be it analog or digital for weather, or tire pressure it is repeatable. If you are looking at information from location X, and then you race at a different track that your information is from Y. It may not be much, but did the car pick up or slow down from weather or ? Just something to think about. How close are most airports to the track, if that is where this information is coming from it makes a difference.
