From Antler Insanity, LLC:
The Antler Insanity (AI) App is an easy to use iPhone program for the serious outdoorsman. Written by outdoorsmen, for outdoorsmen. How many times have you needed to know the wind speed and direction at your favorite location, save and store your locations for later viewing on a map, mark and map property boundaries and game trails, share your spots with other club members or friends, keep notes about your favorite spots, sunrise/set times, or walk to or your favorite spots in the predawn hours before the sun rises and you can see? This app makes all that possible, right in the palm of your hand. Continued use of GPS running in the background can dramatically decrease battery life. Features: The ability to obtain current wind speed, direction, and weather at your GPS location using either World Weather Online (WWO) or National Weather Service (US only). This becomes extremely important when you are deciding whether to hunt there or not. if the wind is not right, then your game will know you are there before you even spot them. You can store the GPS location of your favorite stand in a database for later mapping and weather information determination. This is extremely helpful because you can retrieve the location later and check its wind data to determine if the spot's conducive to success prior to going there. Mark property boundaries and get acreage and save it, mark game trails and save them. Export / Share your Stand List with other AI iPhone App Users. A GREAT feature for hunting clubs, friends, family, etc.You can keep notes or a journal with your marked stands. You can also edit the name of a stored location if you decide to rename it. The app computes sunrise and sunset times for your current GPS location. The calculations are actually performed internally without the use of charts. Data used in these formulas are your GPS location, calendar data, UTC time and the iPhone's current time zone (determined via cellular connection). A set of scoring sheets for selected antlered species (deer, elk, pronghorn, caribou). AI only uses gross scores (no deductions) as we believe your harvest should be judged upon all the bone it has grown. (Scoring worksheets for more antlered species will be added in subsequent versions). The app loads the "Insane Shop" from the internet so you can get some cool stuff, as well as it provides links to AI's Twitter and Facebook pages. This will let you keep up to date with all of AI's hunting expeditions and blogs. Comments: The iPhone Location Services must be turned on for the GPS location features to be used. The GPS locator is best used when the user is outside so a more accurate determination of location can be found. The sunrise and set times are computed internally in the app using your GPS location, calendar information, and time zone location as input into actual mathematical equations. Any differences between the AI computed times, as compared to published charts, could be due to round-off differences in the number of seconds. Continued use of GPS running in the background can dramatically decrease battery life.
