This thread is made for you guys out there that are still resistant of buying a smart phone and for those that aren't taking advantage of it's full potential. There are literally millions of applications out there for smart phones. Most are stupid ad-filled, useless games. Nevertheless, some are VERY useful, and all were FREE! So, lets go over what your smartphone can do or be... Flashlight Most smart phones have a flashlight function through the flasher. My HTD Droid actually has a flashlight with multiple brightness settings and can be very useful. Pocket Medic Certain applications like Epocrates and iTriage can literally save you a trip to the doctor. By simply clicking on the area of your pain or problem area and scroll through the list of symptoms, you can diagnose yourself and find out the appropriate treatment without ever seeing a doctor. Pocket Witness A lot of people forget that their phone can be a huge help in the most stressful situations. Most people forget that their is a camera on their phone and that if they get into an accident they should take pictures of the damage and try to get a wide angle to portray who was actually at fault. You can also take pictures of key land features as you hike so that you don't get lost on the way back. Also, you can download recording apps that record phone conversations or just record anything that is being said within earshot of the phone's microphone (special note that you should be aware of your state's law when recording someone, especially phone conversations). Reference to Critical Tasks You can download full manuals like the US Army's Survival Manual, and WikiDroid. With the latter, I downloaded the top 10% English viewed pages on my phone (although I had to upgrade the SD card to do so). I also have KnotsGuide, a complete reference to any knot imaginable. I also have ElectroDroid, which is a complete reference on anything electrical from battery AMP hours to rewiring your house. That's all I can think of for now...other great apps I have for my phone are: *Maps Ruler 2 (tells you the distance from two points on a map) *Mil Dot Calculator (converts how many mil dots are needed versus how big a target is) *IPSC Shot Timer (cool little timer app for range days) *Smart Compass (an interactive, electronic compass) A lot of these apps were reviewed from an article off of SurvivalBlog.com, so I can't take a lot of credit for the great finding of these applications. Other's were recommended to me by friends. Are there any applications that you recommend? Obviously some of these are specifically for the Droid HTC phones (although I'm sure there are iPhone versions of them) but feel free to add your favorites!
