I have the PlaneFinder HD app running on an iPad 3. It appears that I can see much more traffic for my area in the SW U.S. on Planfinder.net than on the app. Is there a reason for this? Right now I have three planes showing on the app when the website is showing at least 30-40. I don't have any filters enabled.
