I love the Antler Insanity app. Been using it for two years. Every time you see something that you don't want to forget or worried you cant remember where it is....hit the "mark your stand" button. Scrapes, rubs, future stand sites, oaks trees, future places to plant, crossing, potential duck holes, etc,etc,etc. All of these sites will be marked on your satellite image for future reference. I am constantly stopping and digging my phone out to mark something...especially as my memory sucks more and more.
