I know this is a hammock forum but a lot of people do camp and hike on this forum (hopefully I wont get to much grief for this). With that being said if there is/were an app for camping/hiking what would you like to see or have it do?

Would it just be a gear list with a weight tally?
Would it be a trip planner that will tell your loved ones or contacts where you are or going to be (GPS location)?

Just a thought. If you could give me a few ideas I would like to play around with building an app. If I can actually build one
