F1 Circuits

For a buck you cant go too wrong with this app if youre an F1 fan It includes Google Earth images of racing circuits from the air which gives a nice sense of the topography and some feel for these circuits locales However it does very poorly with the many street or temporary circuits in that it includes only a map of the vicinity in which these events occurred ie theres no trace outline of the circuits themselves I happen to know the Long Beach Phoenix Montreal and Monaco circuits routes so I can suss them out on the map but I have no idea about Valencia and Singapore for example and this app offers exactly zero insight If the developers are serious about doing more than linking their app to a Google Earth hit they really should add a trace overlay for the tracks in question The linked Wikipedia pages provide some guidance with respect to circuit layout but they dont place the layouts on the map Also this would have even more value if there were some missing circuits like Detroit Dallas and Las Vegas now buried under a building thats part of Caesars Palace Its not all that difficult finding information about location and layout for those tracks using Internet resources           Good start easily could be better
