the only time I use my phone dirning hunting is right up to the season start. I went elk hunting for 8 days last year and I was there two days before the season and that was the only time I uwsed my phone. Once the season started it was put away....I am there to hunt not play on my phone....I enjoy the company and the outdoors and that is enough for me. they are nice to have just in case, but last year has been the only time my phone has worked while hunting.
Many states now allow a hunter to call in their harvest while still in the field so cell phones while hunting will remain a constant until some other technology takes over.
The only app I would be interested in would be one that told me/notified me of the 1/2 hour before sunrise time and the 1/2 after sunset times.
Many hunters now keep a diary or log of their hunts. That could be usefull as an app but typing it up on a cell phone key board is a nightmare. Also - heard of a very inexpensive software for voice recognition - install that and this hunt log app would then be easy.
Any of these ideas used I expect a contractual agreement to pay me risiduals for life and afterwards to my children.
I also tried looking up this Deer Diary on Facebook and couldn't find it. Must be a bust or under another name?
Found their web site - here it is - http://www.deerdiary.com/ Some of the items already offered on the app - except I don't see voice recognition dictation of a log or the ability to show GPS legal start and stop hunt times.
I take my iphone hunting all the time, mostly for time and weather conditions. My brother, dad and I stay in contact through text which nice and we stay updated on our hunt. Sometimes you may be late out of stand becuase deer are around so you can simply text who your hunting with to let them know so they don't come looking for you or worry. Being a small business owner, it's a way I can respond to emails I may miss while hunting.
As far as app for hunting, I can't think of any off hand. Although, next time I'm out I try to think of something.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
