Huntstand is a cool app. So is Weather Undergound for weather forecasts. Heard AccuWeather is pretty good, also.
The Huntmore App is a really cool photo sharing app for all things hunting related. There's so many private groups/pages for the same topics on FB that a guy can almost get lost trying to navigate. How many shed antler pages does there really need to be? What's great about the Huntmore App is every topic you can think of in hunting has a category for it and folks publish photos directly to those categories. You can follow people, similar to Instagram, only without the hash tagging because content is already in the categories they apply to.
The other cool thing about the Huntmore app is that everyone on there is supportive of one another, no trollers and internet cowboys picking on each other.
