I got the app a few weeks ago and havn't had time too check.Used my iphone too ckeck out radar at ABA nationals before we decided too make the 35mi run.Best toy-tool i got in awhile.I think the last toy thing i got that helped catch fish was a loran then gps can along.Knowing where you are on the Great lakes and can't see shore was a big help.I really like my iphone.
