Downloadable offline maps is perfect for those without service or wifi. Location search is needed and accidentally remove pins too easy just trying to deselect them. But overall excellent. Fried every other map Prog and gps maps and this is the winner. It just needs what google has and visa versa. Sometimes seems offline maps dont show so sorta iffy there but was free and believe still is so why people complain. Its better than $10 gps apps Ive bought since they dont work if you dont have cel service. The app does need a way to notify about errors in maps. I notice lately seems my house is area 51 since its recently been removed from all map sites and the roads are wrong. So be nice to have that added
